YOUR BIKES, YOUR WAY<br />

Tony Edwards, it’s fair<br />

to say, is obsessed with<br />

Harris Magnums. He’d<br />

never seen a Kettleengined<br />

Magnum 2, so he<br />

set about building one.<br />

Two years (and thirty four<br />

grand later) here it is<br />

Words: Mark Graham Pictures: Jason Critchell<br />

Tony has a thing about Harris<br />

Magnums. Has done since he was<br />

16. And it shows no sign of going<br />

away. This is his third Magnum,<br />

without a smidgeon of doubt his best to<br />

date, and one to stand among the very best<br />

of the genre. Plus, we think it’s the only one<br />

packing two-stroke power.<br />

These were, along with Moto Martins, the<br />

special frame of the ’80s, although the first<br />

Magnum appeared in 1973 when Seeley,<br />

Rickman and Dresda were still the big<br />

names in trick frames. The Magnum 2,<br />

introduced in 1982, then became the<br />

benchmark in bespoke tubing for big-inch<br />

engines. Geometry, bending and brazing<br />

was by Steve and Lester Harris, Anglo-<br />

German firm Target Design (of Katana fame)<br />

styled the bodywork.<br />

Perimeter-style in Reynolds 531 tubing,<br />

the engine became a stressed-member of<br />

the chassis and most big four-strokes of the<br />

time found their way into Magnum 2<br />

frames; Z1000s, Suzuki GSX11s, Honda<br />

“I’M NOT NORMALLY THE BEST AT<br />

FINISHING THINGS, BUT I TOLD<br />

MYSELF I’D HAVE TO DO THIS ONE<br />

PROPERLY DOWN TO THE LAST NUT”<br />

TONY’S ADVICE<br />

1. Whether it’s the amount of<br />

time you think something will<br />

take, or the amount of money you<br />

think it will cost – double it.<br />

2. Trust specialists to get things<br />

right in their own time. Nobody<br />

appreciates being hassled when<br />

they’re in the middle of a job<br />

(whether it’s yours or someone<br />

else’s). It pays to be patient.<br />

3. If something doesn’t look right<br />

when it goes on, it’s not going<br />

to look any better later. All that<br />

happens is you’ll say to yourself<br />

‘I wish I’d changed that’. Change it<br />

or all that’ll happen is you’ll regret<br />

it later.<br />

CB900s and Laverda Jotas. No Kettles in a<br />

Magnum 2 – until now.<br />

“I love that ’80s endurance look,” says<br />

Tony. “They were the first proper specials I<br />

saw and such beautiful pieces of<br />

engineering.” Those first glimpses of<br />

Magnum 2s gave him a taste for specials<br />

building too.<br />

“My mate had a Suzuki RM250<br />

(motocrosser, although you’d have called it a<br />

scrambler back then) and he’d blown his<br />

motor. I had a DT175 engine lying around<br />

so we put that in it. It was all the wrong way<br />

around really, ideally you’d have put the RM<br />

engine in the DT, but it was a good learning<br />

process,” he says. “I wish I’d kept that bike.<br />

But then we all look back and say that about<br />

all sorts of things.”<br />

This Magnum Kettle is likely to be a<br />

keeper though. Two years in the making,<br />

Tony went flat out to make sure he got<br />

everything perfect. “I’m not normally the<br />

best at finishing things,” he admits. “But I<br />

told myself I’d have to do this one properly<br />

down to the <strong>last</strong> nut.” To all intents and<br />

purposes he’s got it all spot-on. But the<br />

uber-perfectionist inside him still can’t rest.<br />

“The radiator hose through the fairing is<br />

something I’d change,” he admits. “But I<br />

can’t think of another way of doing it.” By<br />

any standards, if that’s his biggest problem,<br />

this bike has got to be existing on a higher<br />

plane than most Magnums.<br />

Take the electrics, traditionally a problem<br />

area on many specials, or at least a part of<br />

the build that’s least appealing to the<br />

majority of builders. Not Tony though. He<br />

went the Motogadget route for switchgear<br />

and wired the whole lot in himself, routing<br />

the ’bar switch wiring internally through the<br />

clip-ons. And the wires are tightly clad in<br />

black braided nylon too. He couldn’t have<br />

done it more properly if he’d tried.<br />

Tony took his time and only finished it two<br />

months ago. “The engine alone took nine<br />

months,” he says. “I don’t believe in<br />

harrassing specialists. The people who do<br />

things properly do them at their own pace.”<br />

Worth the wait though. How about 96bhp<br />

and 72lb.ft of torque at the rear wheel. “It<br />

was putting out 102bhp but we decided to<br />

knock that back a bit on the ignition curve<br />

for the road.”<br />

The power unit is a 1972 GT750J engine<br />

worked over by BDK Race Engineering in<br />

Ashwellthorpe in rural Norfolk. And they<br />

truly went to town on it: O-ring head<br />

gaskets, downdraught carb inlets, lightened<br />

crank, meticulously matched porting job,<br />

RGV250 alternator, magnesium side covers,<br />

Zeeltronic programmable ignition,<br />

“The 38mm Mikunis are on a 20-degree<br />

downdraught,” says Tony. “The engine has<br />

been angled down in the frame slightly too,<br />

but the carbs kept flooding no matter what<br />

we did to the float heights.” The solution? “I<br />

found some angled inlet rubbers for a<br />

CZ490 motocrosser on eBay. The poor bloke<br />

couldn’t work out why I wanted three of<br />

them. But they were sent from Czecho and<br />

did the trick.”<br />

The radiator was originally a GSX-R750<br />

K1 item but it fractured on its solid<br />

mountings during dyno testing and the only<br />

replacement to hand was a ZX-6 item that<br />

fitted like it was made for the job. “It went<br />

straight on and now it runs without a<br />

thermostat with the electric fan set to chime<br />

in at 95-degrees.”<br />

The chassis, with an original NWS ally<br />

swingarm, was treated to exactly the same<br />

level of attention as the engine. “The<br />

headstock’s original, but the front tubes and<br />

engine mounts are all new,” says Tony. “Mal<br />

at Metal Malarkey (nr Bishop’s Castle,<br />

Shropshire) did a great job. You’d simply<br />

never know. Most of the frame work was to<br />

get the front mounting points absolutely<br />

right. He welded up the Swarbricks too, just<br />

to make sure they fitted perfectly.”<br />

Swarbricks come in kit form, cones and<br />

tapers all cut and rolled from mild steel<br />

ready to be tacked together for fit and then<br />

finish-welded when it all falls into place. This<br />

way there’s no bodging brackets and dinging<br />

dents to make it all work. The neatness is<br />

palpable, especially in the ceramic-like<br />

Thermakote finish.<br />

Finish is, of course, everything on a special,<br />

and Tony has gone very deep into the ’80s<br />

vibe with a 1984 Shell Oils style paint job<br />

on a red frame (from a Harris brochure no<br />

less) that fairly screams ’ARRIS MAGNUM!<br />

Which is entirely understandable. “I saw that<br />

paint job when I was 18,” says Tony. “And<br />

not having the money then meant I just had<br />

to do it now.”<br />

The three-spoke Dymags are off a V&M<br />

race bike and came cheap because they’re<br />

five pin cush-drive items, not the more usual<br />

six. “It didn’t matter to me because we were<br />

making a new cush-drive set-up anyway.”<br />

Just like Tony and Mal made the myriad<br />

spacers and mounting plates for the rearsets,<br />

and the Aprilia Mille R brake discs and<br />

Pretech calipers.<br />

It really is a Special Brew a Magnum,<br />

always were and always will be because<br />

there are so many variables involved in a<br />

“I FOUND SOME ANGLED INLET<br />

RUBBERS FOR A CZ490<br />

MOTOCROSSER ON EBAY AND<br />

THEY DID THE TRICK”<br />

build that’s purely a frame (in this case<br />

originally purposed for a GSX1100) glass<br />

fibre body parts – and the rest is entirely up<br />

to the builder. Which means it’s more than<br />

possible to take a wrong turn.<br />

“The bike came with upside-down Öhlins<br />

forks and I thought they’d be fine, but once<br />

the Kettle engine went in they just didn’t<br />

look right at all,” says Tony. “You’d think<br />

anyone would be mad to swap them, but I<br />

just bit the bullet and bought a pair of<br />

conventional Öhlins.<br />

“Then there are the magnesium engine<br />

covers which shave a very welcome three<br />

inches off what is a wide engine. The<br />

alternator cover is carbon fibre and I’d<br />

rather have it plain magnesium because the<br />

carbon is not really of the period, but I’ve<br />

got to draw a line at having one CNC’d.<br />

Along with that hose through the fairing it’s<br />

another bugbear.”<br />

So, two perceived problem areas on a bike<br />

that are ‘only’ cosmetic is not a bad result.<br />

When the whole thing gels so well to a<br />

casual onlooker, it’s only Tony who’s ever<br />

going to be mildly unsettled by what he sees<br />

as flaws. Will he get around to fixing them?<br />

Not while he’s working on a turbo-charged<br />

Aprilia 125 that’s already making 28bhp<br />

without a blower. “I’m hoping to get more<br />

than 40bhp. There’s a bloke in Sweden<br />

who’s got 54bhp at the crank from a turbo<br />

TZR125, so it’s possible,” he says.<br />

And when he’s not attempting to squeeze<br />

impossible power from 125s he’ll be<br />

tear-arsing around on his Bandit-engined<br />

Magnum 4, or enjoying the local lanes on<br />

his Husky 310.<br />

Tony is 53 and runs his own air-con service<br />

company. He freely admits he’s spent<br />

£34,000 on this Magnum Kettle. “The<br />

missus knows I’ve spent more than 30 grand<br />

on it. The engine alone was 10 grand.”<br />

Where some people are oddly guarded<br />

about how much they spend, Tony is the<br />

polar opposite and is quite happy to confess<br />

just how much he’s into this one-off<br />

Magnum stroker for.<br />

You can see how utterly stiff the Harris tubework is with the engine as a stressed<br />

member – few headstocks are as strong and unyielding as this<br />

Money is a means to enjoy the good things<br />

in life; Magnum to Tony means Harris, not<br />

champagne. “I couldn’t even get a<br />

Desmosedici for what I’ve spent on this,” he<br />

says putting the vast expense into some sort<br />

of perspective. Not that he’d want one. Not<br />

when there are other Harris Magnum builds<br />

waiting to be dreamed and schemed and<br />

brought to life.<br />

“An engine spinning up<br />

to 18,500rpm qualifies<br />

it as ‘exquisite’ and, if<br />

you must, ‘jewel-like’ ”<br />

HONDA<br />

CBR250<br />

One of the true grey import gems of the late-<br />

’80s, the rev-ravenous junior CBR is still a<br />

thing of great wonder to behold (and ride)<br />

Words: Alan Seeley Pictures: Bauer archive<br />

Honda can’t do small<br />

without such adjectives<br />

as ‘exquisite’ and ‘jewellike’<br />

being immediately<br />

applied in description of their<br />

creations. However in the case<br />

of the 1986 CBR250R and its<br />

direct descendents they are totally<br />

apposite. No wonder it became one<br />

of the most prized grey imports.<br />

A double overhead cam – cams<br />

driven by gear – 16-valve inline<br />

four engine, each of those pistons<br />

just 48.5mm in diameter, capable of<br />

spinning up to a claimed 18,500rpm<br />

probably does qualify as ‘exquisite’<br />

and indeed, if you must, ‘jewel-like’.<br />

The CBR250 is wholly typical of<br />

just the kind of thing Honda used<br />

to do brilliantly. The model in the<br />

current Honda range that now<br />

carries the name, an Indonesianbuilt<br />

parallel twin clad in geometric<br />

p<strong>last</strong>ic, shows just how far they<br />

haven’t come.<br />

When the CBR250 appeared – the<br />

proper one that is – the 250 class<br />

was one of the most competitive<br />

in Honda’s domestic market. The<br />

quarter-litre race classes were<br />

among the most-hotly contested<br />

and a focus for development by<br />

all of the Japanese manufacturers.<br />

The 250 sector was vital for sales<br />

too, these bikes were exempt from<br />

Japan’s exacting bi-annual Shaken<br />

test; an expensive and onerous<br />

MoT-type inspection.<br />

So with that exquisite and, erm,<br />

jewel-like engine installed in an<br />

aluminium twin-spar frame which<br />

was augmented with a swooping<br />

Gull-arm rear swinger for the 1990-<br />

on CBR250RR, the recipe could<br />

only be a good one.<br />

The first model, the 1986 CBR250<br />

Four MC14 featured a half-fairing<br />

and a drum brake in the cast rear<br />

wheel. However with the arrival<br />

of the CBR250RH MC17 a year<br />

later, the quarter-litre inline-four<br />

suddenly looked a lot more sporty<br />

featuring a full-fairing and a disc<br />

rear brake replacing the drum. The<br />

‘Hurricane’ legend across the fairing<br />

promised a bit of poke too.<br />

However it was the MC22<br />

CBR250RR of 1990 that really gave<br />

the CBR its best sportsbike lines.<br />

So it was a shame that Japanese<br />

domestic legislation dictated a drop<br />

in power from 45bhp to 40 for ’94.<br />

The <strong>last</strong> of the line were built<br />

in 1996 although a few were<br />

registered after that. Honda<br />

continued to recognise the genius<br />

of the gear-driven cam 250 four<br />

engine, and it was still offered in the<br />

CB250 Hornet as late as 2007.<br />

For now, they’re not that easy to<br />

come by here. If you can find a fullpower<br />

MC22, hold onto it.<br />

WHAT TO LOOK FOR<br />

1 Engine<br />

Exquiste and jewel-like (as we<br />

may have mentioned). Does<br />

best if oil is changed every<br />

3000 miles. Can rattle like<br />

a bag of cheap spanners if<br />

owners switch to full synth.<br />

2 Exhaust<br />

Clunky one-piece exhaust<br />

systems on all models prior to<br />

the MC22 mean that if part<br />

of it rots out, the whole thing<br />

is scrap. MC22 fares slightly<br />

better as at least the end-can<br />

is separate. MC17 pipes<br />

were stainless, albeit it cheap<br />

stainless.<br />

3 Reg/rec<br />

Known weak point, or more<br />

accurately, the connectors<br />

and wiring tend to be the main<br />

<strong>issue</strong> leading to premature<br />

failure of the reg/rec unit.<br />

Clean and check earths.<br />

4 Brakes<br />

Sliding calipers need to be<br />

cack-free and lubed if to do<br />

what they’re designed to do.<br />

5 Shock<br />

Soft originals no longer<br />

available but decent<br />

aftermarket units are.<br />

6 Bodywork<br />

Original panels hard to find so<br />

check condition carefully.<br />

7 Carbs<br />

Small carbs means small jets<br />

which also means that blocked<br />

jets aren’t uncommon. At least<br />

they’re easy to access.<br />

8 Derestriction<br />

No easy business as the 1994-<br />

on bikes were restricted in the<br />

cylinder head, head gasket and<br />

CDI unit. Buy an earlier one<br />

or buy another bike if you’re<br />

bothered by the loss of 5bhp.<br />

HONDA CBR250<br />

Some we found earlier...<br />

£3995<br />

s 1989 Honda CBR250RK MC19<br />

Listed by the vendor as a 1996 model, this bike’s<br />

features (including its G-reg plate) would point to<br />

it being a 1989 MC19. It’s pretty clean and there’s<br />

just 22,000 miles been covered. Nikko Racing<br />

aftermarket exhaust.<br />

£800<br />

Oil change<br />

WORKSHOP RATINGS<br />

20 mins<br />

You’ll be in and out fairly quick on the halffaired<br />

MC14, allow a little longer to get<br />

the fairing lowers of the others. Use a good<br />

semi-synth oil.<br />

Spark plug change<br />

40 mins<br />

Not so bad once you’re in there. Give the plug<br />

recesses a b<strong>last</strong> out with compressed air<br />

before removing the plugs.<br />

Top end rebuild<br />

2 Days<br />

Only complicated by lots of small parts on<br />

the 16v head. Valve adjustment is by shim<br />

under bucket – so it’s cams out.<br />

Engine rebuild<br />

3 Days<br />

Gear-driven cams throw a few more cogs<br />

and bearings into the mix but there’s nothing<br />

too daunting here. Clutch-holding tool and<br />

flywheel puller will prove beneficial.<br />

Fork oil change<br />

3 Hours<br />

Legs out and disassemble for a proper drain<br />

and clean, if you please.<br />

Brake pads<br />

20 Minutes<br />

Clean calipers, especially the sliding pins and<br />

pistons at pad-change time. MC14 has a rear<br />

drum which takes a little longer to change the<br />

shoes on.<br />

s 1987 Honda CBR250R MC17<br />

Recently sold in a classified ad on eBay.<br />

Imported to the UK back in 1997. Needs some<br />

tidying and sometimes runs on three.<br />

Will want tyres and an MoT. How much do you<br />

want for £800?<br />

Carb strip/clean<br />

4 Hours<br />

Easy to access and to remove and refit.<br />

Simple to work on and Mikuni spares are<br />

easily available. Balance to avoid vibes.<br />

The four 29mm Mikunis are easy to remove and<br />

refit, and all spares are readily avaialble<br />

Some of the best<br />

things in life come in<br />

small packages. And<br />

the wee CBR is no<br />

exception to the rule<br />

CBR250s are getting<br />

harder to come by<br />

these days. And prices<br />

are reflecting that.<br />

Occasional dealer sales<br />

for good ones are now<br />

nudging five grand plus<br />

We have frame start numbers for each<br />

model only. Engine numbers don’t<br />

match in any case.<br />

Looking for something less conventional?<br />

Fancy riding something left-field? <strong>PS</strong> brings<br />

you our pick of the weird, wild, wonderful,<br />

often good value, and downright bizarre...<br />

When Wankel engines<br />

looked like the future<br />

Practical Sportsbikes 69


Oddball bikes<br />

Aimed squarely<br />

at the USA,<br />

yet still wilfully<br />

weird<br />

Yamaha FZX750<br />

1986-1988 749cc liquid-cooled, dohc,<br />

20v inline-four, 94bhp, 204kg<br />

What is it? Factory hot-rod powered by Yam’s<br />

epic 20-valve inline-four; if the V-Max and FZ750<br />

got it together, this would be the result.<br />

Why so odd? Like corn-dogs, waxy chocolate and<br />

reimagined historical events, the FZX Fazer was<br />

aimed squarely at the American market. Lazy<br />

raked-out steering, nitrogen sealed-cell twin<br />

shocks, awkward blocky styling, and bizarre<br />

16/15-inch wheels were never going to have<br />

Europeans reaching for their wallets.<br />

Why you want one: The FZ-derived motor is<br />

an absolute peach. Flexible, powerful and<br />

willing to launch a tidal wave of torque in any<br />

gear and any revs, it suits the FZX’s street rod<br />

intentions to a tee. Launch this thing away<br />

from the lights and little else will keep up. Just<br />

don’t expect to whip around the fast<br />

approaching corner with any ease.<br />

Values: £500-£2500<br />

Harley-Davidson VR1000<br />

1994-1995 996cc liquid-cooled, dohc, 8v<br />

60-degree V-twin, 135bhp, 176kg<br />

What is it? All-American superbike, ultimately<br />

doomed by a lack of on-track success and a horrific<br />

price tag.<br />

Why so odd? It looks like nothing else, and its<br />

development story saw all sorts of left-field ideas<br />

(many from Erik Buell when he was involved, like a<br />

fuel-in-frame design that was eventually dropped).<br />

It’s very un-Harley, too – whether that’s good or<br />

bad is up for debate – having had everyone from<br />

Harris to Cosworth involved in the build process .<br />

Why you want one: Underneath it all, however, is a<br />

sweet-handling superbike that’s refreshingly and<br />

deliberately unlike its European or Japanese rivals.<br />

But only 55 were built for homologation purposes<br />

and at $49,000 new (later reduced to $34,000),<br />

finding one could be a life-long search. And when<br />

you do, it ain’t gonna be cheap or anywhere near as<br />

good as a Ducati.<br />

Values: £30,000-plus<br />

Ducati Paso<br />

1986-1992 749cc a/c, (904cc l/c) sohc, 2v<br />

90-degree L-twin , 72bhp (90),195kg (205kg)<br />

What is it? An Italian sports tourer; the result, we<br />

suspect, of an extremely boozy lunch.<br />

Why so odd? There was never going to be a time<br />

the world would be truly ready for the Fabio<br />

Taglioni designed Paso. It looks as deliberately<br />

bonkers today as it ever did, and that is a large<br />

part of its distinctive charm.<br />

Why you want one: Go for the later 907ie and<br />

you’ll have a comfortable, capable, if slightly<br />

daft-looking, continent crusher with an undeniably<br />

Latin flavour. If you’re going to buy Italian, you may<br />

as well jump in with both feet, right?<br />

Values: £2500-£4000<br />

“IF YOU’RE<br />

GOING TO BUY<br />

ITALIAN, YOU<br />

MAY AS WELL<br />

JUMP IN WITH<br />

BOTH FEET,<br />

RIGHT?”<br />

Named after the great<br />

Italian rider Renzo<br />

Pasolini. Not sure he’d<br />

have been too happy<br />

about that<br />

Blame Bimota<br />

and theirTesi<br />

for efforts<br />

like this<br />

Yamaha GTS1000<br />

1993-1994 1002cc liquid-cooled, dohc,<br />

20v inline-four, 102bhp, 246kg<br />

What is it? Tech-packed sports tourer that was<br />

just too far ahead of the curve to be a success<br />

back in the 1990s. A pig to work on, too.<br />

Why so odd? There hasn’t been a satisfactory<br />

upgrade on the humble telescopic fork as yet.<br />

Many have tried, but none have proven<br />

significantly better to consign the tele to the<br />

dustbin of history. Yam had previously shown<br />

us the Morpho 400 concept bike, but the<br />

production version – the GTS1000 – wasn’t<br />

any better than, say, a CBR1000, despite<br />

all its tech.<br />

Why you want one: It’s unlikely any<br />

manufacturer will build a bike like the GTS<br />

again. It represents a moment in history, albeit<br />

an unsuccessful one. Even so, the GTS isn’t a<br />

bad bike, and as a comfortable tourer it excels.<br />

Having an EXUP motor doesn’t hinder it either.<br />

Values: £1500-£3000<br />

Yamaha Zeal 250<br />

1991-1992 249cc liquid-cooled, dohc, 16v<br />

inline-four, 40bhp, 145kg<br />

What is it? Short-lived Japanese market street<br />

four with a strange mix of old and new tech.<br />

Why so odd? Any bike styled to mimic a swimming<br />

dolphin, as the Zeal apparently was (we can’t see it<br />

either), is by definition a bit odd. Despite an<br />

FZR250 derived engine with a 14,500rpm rev<br />

ceiling, the Zeal is softer than a marshmallow on a<br />

bed of feathers. Even in Japan’s monstrously<br />

gluttonous home market of the early 1990s the<br />

Zeal only managed two years in the range before<br />

being given the flick.<br />

Why you want one: If rarity value presses your<br />

buttons you may well covet this strange Yamaha,<br />

but if that’s the case hang out for a Honda Hornet<br />

250 instead. It’s a better bike in every respect.<br />

Values: £800-£2500<br />

Honda VF750S<br />

1986-1988 748cc liquid-cooled, dohc, 16v<br />

90-degree V4, 82bhp, 225kg<br />

What is it? A whole lot of trouble, and the worst<br />

possible showcase for Honda’s then new V4 layout.<br />

Why so odd? Honda’s V4 tech was always<br />

supposed to be the springboard for a new range of<br />

sports and race bikes, so the firm’s decision to<br />

Nice leathers, not so<br />

sure about the lid, dead<br />

certain about the bike<br />

though – shocking<br />

launch its first road going V4 in the<br />

semi-cruiser 750S was odd to say the least.<br />

It proved horribly unreliable and even a step<br />

too far for the Americans. A disaster in every<br />

respect. It almost sank the whole project.<br />

Why you want one: Trust us, you really don’t.<br />

Ever. An early VF750F with its factory recall<br />

mods, now that’s a different proposition<br />

entirely.<br />

Values: £700-£1800<br />

Kawasaki Xanthus ZR400<br />

1991-1992 398cc liquid-cooled, dohc, 16v<br />

inline-four, 53bhp, 168kg<br />

What is it? Barking, that’s what. No manufacturer<br />

has built anything like the Xanthus (Achilles’ horse<br />

in Greek mythology) before or since – a shame.<br />

Why so odd? Back in ’92 with its twin-stacked<br />

silencers and multi-sectioned aluminium frame the<br />

Xanthus screamed modernity in a way that made<br />

even cutting edge sportsbikes of the time look<br />

ordinary. Almost a quarter of a century later the<br />

Xanthus still packs a mighty visual punch.<br />

Why you want one: ZXR400 motor in a bonkers<br />

chassis, stripped back and naked for all the world to<br />

see. Being a home market model, and only here as a<br />

grey import, this 400 Kwak is a rare find too, so it’ll<br />

always pull a crowd. The stock cans are a must.<br />

Values: £1500-£3000<br />

Oddball bikes<br />

Gilera CX125<br />

1991-1992 124cc liquid-cooled, reed valve,<br />

two-stroke single, 30bhp, 125kg<br />

What is it? The maddest production 125, or<br />

indeed two-stroke, ever built.<br />

Why so odd? Single-sided swingarms front and<br />

rear, near solid wheels, all enclosed bodywork and a<br />

look only matched by the off-the-wall Elf racers,<br />

the CX looked like it had dropped from another<br />

galaxy, never mind planet, when Italian marque<br />

Gilera unveiled it in the early 1990s. Sadly its<br />

oddness worked against it – Italian kids viewed the<br />

CX as kudos-shrivelling, so sales slumped.<br />

Why you want one: The CX’s lack of sales success<br />

mean it’s a true rarity today. There is nothing else<br />

like it, of any capacity, and it’s become a cult classic<br />

in recent years. Values are soaring, too. They remain<br />

resolutely a love/hate machine, however. We love<br />

them.<br />

Values: £2000-£3500<br />

The Italian market<br />

failed to embrace this<br />

CX – so it bombed<br />

Norton Rotary Classic<br />

1987 588cc air-cooled, twin chamber rotary,<br />

79bhp, 227kg<br />

“ODDEST OF ALL, IT FORMED THE BASIS<br />

FOR BRIAN CRIGHTON’S HUGELY<br />

SUCCESSFUL RACERS”<br />

What is it? A better attempt at the rotary theme<br />

than Suzuki’s RE5, but still odd in almost every<br />

respect.<br />

Why so odd? The wankel engine had no connection<br />

to the earlier Norton name, but it kept the brand<br />

alive for a further decade or so. Oddest of all, this<br />

utilitarian roadster (check out the almost Eastern<br />

Bloc styling) formed the basis for Brain Crighton’s<br />

hugely successful Norton rotary racers.<br />

Why you want one: Like the RE5, this is a bike with<br />

a massively enthusiastic cult following and those<br />

who run them, love them. Although thirsty, a rotary<br />

motor has a charm all of its own. Pricey though.<br />

Values: £6000-£10,000<br />

They spent some money on this photo shoot<br />

(money they could have spent on the styling)<br />

Suzuki RE5<br />

1974-1976 498cc liquid-cooled single chamber<br />

rotary, 62bhp, 230kg<br />

Suzuki VX800<br />

1990-1996 805cc liquid-cooled, sohc, 4v,<br />

45-degree V-twin, 61bhp, 213kg<br />

What is it? It’s doubtful even the VX800 knows<br />

what it is – a cruiser? Street bike? Who knows?<br />

Why so odd? Fitting a cruiser lump into a street<br />

bike(ish) package with lazy steering and shaft-drive<br />

isn’t a great recipe. But the VX was part of Suzuki’s<br />

range for six years – in the UK.<br />

Why you want one: If you want to, ahem... cruise,<br />

without all the baggage of bandanas and tassled<br />

chaps the VX makes a lot of sense in its <strong>mixed</strong> up,<br />

muddled up fashion.<br />

Values: £1400-£2000<br />

Kawasaki Eliminator<br />

1985-’86 (900) 1987-’88 (1000) 908/997cc<br />

l/c, dohc, 16v four, 105/110bhp, 238/244kg<br />

What is it? A Mad Max machine made production.<br />

An attitude packed street rod with the heart of a<br />

GPZ900R and later 1000RX.<br />

Why so odd? The Japanese didn’t make many hot<br />

rod genre bikes – Yamaha’s V-Max filled that gap<br />

almost all on its own – but Kawasaki’s offering,<br />

the Z900 Eliminator (and latterly 1000), made<br />

brutal, almost uncomfortably ugly styling a<br />

staple of the class, and all the better for it.<br />

Why you want one: The Eliminator may not go<br />

around corners with anything like the finesses<br />

of its engine donor, but for rolling burn-outs and<br />

lightning fast starts this Kwak is very much the<br />

guvnor. Good value too.<br />

Values: £1200-£2500<br />

What is it? The result of Suzuki’s dalliance with a<br />

technical cul-de-sac that was rapidly killed off by<br />

the sharp rise in the cost of fuel and the fact the<br />

firm’s other less complicated offerings were better<br />

in every respect.<br />

Why so odd? Neither a two-stroke nor four-stroke<br />

but delivering elements of both, the wankel motor<br />

can produce massive performance, especially in a<br />

light bike. But the RE5 was big, heavy (a gargantuan<br />

230kg dry), thirsty and no match for Suzuki’s more<br />

conventional GS750.<br />

Why you want one: Like a factory turbo, own one<br />

for the sheer hell of it. Those who own RE5s, love<br />

them. Plus there will never be another Japanese<br />

rotary.<br />

Values: £5000-£12,000<br />

Suzuki GSX400X<br />

1986-1987 398cc liquid-cooled, dohc, 16v<br />

inline-four, 59bhp, 153kg<br />

What is it? Proto streetfighter with angular styling;<br />

like a second-generation Katana.<br />

Why so odd? It was a proper one-off, spawning no<br />

updates or secondary models, despite its base<br />

being boringly conventional – GSX-R400 motor,<br />

parts bin wheels, forks, etc. Being a Japan only<br />

model, the 400X was up against the then manic<br />

interest in pure sportsbikes, and the appeal for its<br />

stripped back style fell between the cracks.<br />

Why you want one: It’s an interesting oddity and<br />

very of its time. Great if you fancy a GSX-R400<br />

without the focussed race rep look. A Honda CB-1<br />

or a Kawasaki Xanthus would be a better bet.<br />

Values: £700-£1500<br />

When Health & Safety meant<br />

not having that fifteenth pint<br />

Styling appeals, price too.<br />

What’s not to like?<br />
