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 />

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 />

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 />

Looking for something less conventional?<br />

When Wankel engines<br />
looked like the future<br />

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 />

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 />
