The Paso 906 was a significant bike for Ducati, their
first to really aim at a slice c' the mass market dominated by the Japanese.
Althoug firmly committed to the merits of a V-twin, Ducati realized that the
days of their air-cooled, two valve,
Desmo un. hung in a lean sporting
chassis were strictly numbered. They needed more power and efficiency, and
they also needed to pass increasingly stringent emission controls. Their ok
bikes were too noisy. Worse still their exhausts pumped an awful lot of
damaging hydrocarbons out into the atmosphere. Ducati needed to clean up and
refine their act, attracting new customers while hopefully not alienating
traditional Ducati enthusiasts.
The Paso 906 was their answer to this
challenge and is in many ways a transitional offering between the fabled
Dukes of old (like the 750 and 900SS) and the truly fabulous bikes yet to
come (like the 851 superbike). Although it looked like a million dollars,
the 906 Paso received a fairly cool reception from road testers and buyers
alike. If was too different from the old Ducatis to attract the cognoscenti
(or Ducotisli), yet it wasn't different or fast enough to attract
buyers of big Japanese sports bikes. It was certainly a brave move on
Ducati's part, but it didn't quite come off. With the benefit of hindsight,
it's easy to see now that it was a convenient halfway house, a bold step
between Ducati's past and future. In the language of the market though, the
Paso looked better than it cooked.

Designed by the then
technical director, Dr Massimo Bordi, the 906 engine is actually 904cc (the
factory obviously didn't feel that 904 Paso had the right ring to it). It
was a new engine, sharing some of the development that would later be seen
on the 851 - both have the same slim crankcases, six-speed gearbox and dry
clutch. But whereas the 851 would carry twin cams and four valve heads, the
Paso was stuck with a traditional Ducati valve-train - a single cam and two
valves, Desmo operated of course. The new engine was
water-cooled and incredibly over-square, the 92mm pistons being much larger
than anything Ducati had previously fitted. Fed by a big twin-choke 44mm
Weber carb, the engine made good power with lots of torque and a new-found
appetite for high revs. The carburetion and ignition seemed particularly
well-sorted. Between 3000 and the 9000rpm redline, there were no flat spots
or huge steps, just straight up, linear power. About the worst aspect of the
new motor was its lack of noise.
The water-cooling handily absorbed any
mechanical clutter but the new exhaust system restricted the distinctive
V-twin rumble to a muffle and doubtless stifled some of its low-down power
too. The box section steel frame, the Marzocchi/Öhlins
suspension and Brembo brakes performed in the time-honoured Ducati fashion,
giving redoubtable handling and a stiff, taut ride. They made a mistake in
fitting 16in wheels front and back though.
The fashion for quick steering
16in front wheels had stemmed from the 500cc GP bikes of the mid-1980s, but
had been superseded by the development and undeniable all-round merit of
17in wheels long before Ducati unveiled the Paso. Arguably overtyred with a
130/60-16 front radial, the steering needs to be firmly wrestled with to
prevent understeer and the bike tends to stand upright if braked when heeled
over. In its favour, the steering response and front wheel behaviour becomes
quicker, predictable and more acceptable the faster you go. But then there's
the problem of the riding position, which is not exactly comfortable or
adaptable and has most riders looking down on the bike unable to fully tuck
in behind the low screen.
The lovely, fully integrated bodywork
created by Italian craftsman, Massimo Tamburini and finished in traditional
fire-engine red, gives the bike forceful visual impact. But for too many
die-hard Ducati enthusiasts, the Paso lacked character. It may have looked
like La Dolce Vita on two wheels but really it was a harbinger of
greater and more potent motorbikes yet to come.
