Something weird seems to happen to motorcycle journalists when they test
Ducatis they try and become writers. Instead of self-fornicating about
'rear-wheel steering', 'squaring-off turns or braking 'deep' into corners they
waste their time trying to convey the EVOcativeness of the Ducati name,
explaining the animateness of its hand-built construction or worse, attempting
to phoneticise the rasping off-beat of the V-twin exhaust. The good news is that
they can only perform this sycophancy once; the bad news is that with the advent
of the 888 they'll probably try and combine both styles of literary onanism.
The reason for this is simply because the big twin can no longer be
considered a cute if largely anachronistic slice of industrial architecture.
Rather, Massimo Bordi's latest incarnation of the classic Bologna prescription
proves there is plenty of life yet in the most traditional of motorcycle engine
configurations and demonstrates beyond all reasonable doubt that the
weight-saving advantages inherent in a twin, can more than compensate for the
marginal power advantages of a multi.
I have to admit that even in the heady days of my youth, I was never a
dEVOtee either of twins generally or Ducatis in particular and in common with
the current 20-23 year old hardcore biking generation (gotta have something in
common with 20-23 year olds) I've always considered Ducati a quaint if rather
uninspiring irrelevance. I even managed to dismiss or more accurately, ignore
their current domination of World Superbike racing on the grounds that perhaps
the formula wasn't really pukka or serious enough, because quite honestly if you
haven't ridden either an 888 or one of the race-kitted 851 s, it's difficult to
imagine that a twin could ever be competitive with a Jap four.

Well, it's time to eat humble pie, hats or any other item of self-deprecating
cuisine because the Ducati can be ridden on the road harder and faster than
almost any other motorcycle I can think of and its handling abilities are the
least of its virtues. On the track too, it's not the 888's agility per se that's
humiliating the opposition, rather it's the devastating torque out of corners
and the yards it puts on the multis before they can achieve similar velocity.
The Ducati is fast; not fast by European, twin-cylinder, or any other equally
idiosyncratic standards; it's fast by any bloody body's standards; incredibly
fast, staggeringly fast, outrageously fast. Fast to the point where even
road-testers and EXUP owners have to back off the throttle. Fast to the point
where the Japanese are now lobbying for a capacity bee they're fed up to
the back-teeth of staring up Roche's rectum.
How ran this be? I know all you cynical adolescents are pondering. How ran a
twin with nothing more innovative than 4-valves per cylinder and a bolt-on
injection kit be laying waste to prior Oriental omnipotence? Perhaps only Mr
Bordi knows; certainly I was just as disbelieving of his claims of 85bhp at the
back wheel for the first 851 back in 1987 and I proved to be looking up my own
bottom then too.
Well first you gotta understand that the 888 is not the888 anyway, which is
why it's only got 851 still writ large on all the fibre. The 888 might be 888,
but it's not die888 which is reserved exclusively for the hand-assembled,
blue-printed, race-shop prepared Lucchi replicas. The road-going 888 is in fact
the SP2 which, of course. version of the larger engine, so that whilst it does
indeed enjoy the extra capacity, it only has Ducati's regular
floor workers* fag-ash down the bores and not the Sobrani Superkings of the
tuning tent. The designation SP or Sport Production does indeed indicate that
it's a very different beast from the basic model but it also informs you that
it's a freely available production line bice.
important changes have oeen installed to gain the extra I5bhp (at the
gearbox) that the 888 boasts over the 1990851 and the most obvious of these is
of course the simple 37mm scrape job. But that ain't all; the SP incorporates
the longer duration cams of the race-bikes plus larger valves, oil-cooler and an
unproved collector box (not to mention the very 'free-flowing' exhaust). The
radical, but significant changes which bequeathe the SP a claimed I 15 brake and
provide it with an urge which is truly irresistable. If you've been brought up
on an exclusive diet of Jap bikes you can barely begin to conceive of what
'true' torque is; it's not the frantic, panic-stricken suddeness of a
multi-valve four at six grand, rather it's the un rest rai nab I e, overwhelming
and overpowering tide of influence right through the rev-range that simply
cannot be resisted. You feel safe and secure in its strength; priviliged and
superior in its 'correctness'. This is quite simply how all road motorcycles
should develop power and it is equally difficult to conceive just how quick
these bikes are out of the turns unless you've ridden one or, of course, watched
them disappear up the track in front of you.
An open, dry, multi-plate clutch is not an ideal accessory for ten-yard
sprints but with I OSkph on tap before you have to change into second, 0-60
times are quite incredible. The sound of a spin-dryer full of cutlery is
slightly unnerving if you ever do find neutral, but in over lOOOkms I found only
the green light (twice) and the appropriate space in the gearbox once (and that
was only when I got shunted from the rear on Bologna's South circular and my toe
stabbed the fever as I exited over the screen). Try and pop a wheel ie (as of
course, you are obliged to in every Italian High St) and the sound of a
spin-dryer full of cutlery changes subtely to a spin-drying full of cutlery
having been sbmmed into reverse—it'll pull
them with ease, but it does not sound happy.
Power is not so pronounced at 6,500 as it is on the Cagiva Elephant version
of the DFI engine, but it's still about the most exciting phase. At 10.500 the
inherent desmodronic valve limrters cut in and the motor cuts out
(sometimes).-.and after first the ratios become a lot closer, possibly too dose
for a road bike between second and third, which, in turn, is the most
interesting cog in the gearbox at the appropriate six and a half grand. Don't
ask me what actual speeds in gears are. because the pull of the mill, is so
acute, that through the acceleration curve, I was having a lot
of trouble focusing— all I know is that fifth comes up after 205kph and I had to
back off at 250kh in top with the motor still willing and urging me on. Ok, an
EXUP will do it for top-end. but it sure as hell ain't the barn-dance for the
japs that it used to be and in the mid-range the Duke's unmatchable.
Whichever one of us was
support-trucking in our demolition-derby Fiat Tipo he could hear the 888
accelerating away for over two miles—this is one hell of a loud motorcycle. With
the 888 within a 50ft proximity, you could not hear the car engine at all or the
stereo or anything else for that matter. ami no matter how accustomed we should
have become to it. the 888 still provided more shocks than a John Carpenter
movie each time it went past. If your idea of fun is splitting a street in two
with the sound of your depature, then this is definitely your cycle, though how
popuar this 'safety feature' proves in anally-retentive old Blighty remains to
be seen.
The difference is, of course, that unlike the average unsilenced Jap four,
the 888 does not promise that it cannot deliver. Traditional in so many
respects, it is untraditional in the way it can be ridden; you don't need to be
a purist nan to make it handle because that wild, snarling beast of a motorcycle
that the Ducati is in traffic, becomes an utterly mild, cooperative, subordiate
pooch on the open road. Do it wrong, and the 888*11 do it right; it is so light
on the move that you can enter a corner at any point, on any line, after course
and still get round it Virgo Intacto. The 888 exhibits none of the chronic
over-steer that plagued the early 851s with their sixteen inch front wheels.
Fact is those early bikes were about as far away from the legend of Ducati
handling as 3-seriesBMWs are from their self-proclaimed reputation for
reliability.

In fact chassis-wise, not much has changed either from those early bikes
that'd stop you dead in your tracks. The aforefi mium led
awful front wheel went in 1989 and the Öhlins 'Upside-Downers' that replaced the
original bog Teles have been superceeded yet again by a set of cunningly similar
items which, it is claimed were designed by Ducati but which are actually
moulded in the and of the Rising Yen. Oddly enough, these are not the awesomely
uncompromising items that you might fear, but are actually about as pliant as
the standard EXUP front-end and, along with the standard Ohl ins rear, complete
the transformation of Italian suspension theory which previously held there was
so such thing as too hard a suspension setting. The rear Öhlins unit.now as much
a part of Ducati as the engine itself, joins the only part of the superstructure
made from box-section, though a further development this year on the 888 is the
addition of the rear sub-frame in alloy. But the rest, the simple tubed
space-frame, weighing nothing and going nowhere, is all that we've come to love.
This particular prescription translates as agility more than anything else;
the ability to turn quickly, to rethink without complaint. With a wheelbase of
only 1430mm and 69 degrees of head you'd be disappointed if it couldn't turn on
its own ass but you don't pay for it in terms of stability. The huge 180 rear
rim gives you more girth than you could use and with the super-sticky Michel in
radials (the best road tyres I have used, ever) it's almost impossible to kick
die back end out. Nor does the front wash-away which makes it the best steering
Ducati I have been aboard; light, neutral, deadly. About the onfy aspect of the
bike's chassis that I was disappointed with was the brakes; it wouldn't hold a
candle to an EXUP going into a turn, but then I suppose it doesn't have to
because it would torch it through the turn and on the gas out of it.
I am told the 851 generally is a great bike to sell on a test ride. It
doesn't matter what people ride to a Ducati dealership, they can't fail to be impressed.
In 1988, no; in 1990 definitely. Across country lanes or mountain passes you
couldn't beat it. On longer bends, jumps and bumps, it feels tauter than an EXUP
and streets ahead of anything else from japan. But what's really important is
that for the first time since the demise of thejotain 1978, this is no longer an
Italian bike's most significant feature.
