HONDA
SP1

After
spending many seasons struggling to keep up with Ducati in the World
Superbike championship, whose rules gave twin-cylinder bikes a weight
advantage, Honda finally abandoned its
traditional V4 engine layout to develop a V-twin of its own. The
VTR1000 SP-1, launched in 2000, proved doubly successful. American
ace Colin Edwards rode a twin to the Superbike world title in its
debut season, and Honda's roadgoing range was enhanced by the arrival
of a superb sports machine.
Despite
its powerful 999cc, 90-degree V-twin motor, high-quality chassis,
race-derived styling and some neat technical features, the HONDA SP1 was
not a limited-edition machine intended solely as the basis for
Honda's Superbike challenger. The model known as the RC51 in the
United States was built in large numbers and priced closer to a
normal sports machine than to its exotic V4 predecessor the RC45.

Honda's
line-up already
contained a big V-twin, but the HONDA SP1 shared fewer
than ten per cent of components with the VTR1000F Firestorm. Its
motor differed in having higher compression ratio, gear instead of
chain drive to its cams, and a close- ratio gearbox. In place of the
Firestorm's carburettors the SP-1 used fuel-injection, fed by an
innovative intake system whose central main duct ran from a fairing
slot between the twin headlights, through the special aluminium
steering head casting to the airbox, reducing the turbulence
generated by normal intakes. Peak output was 136bhp at 9500rpm.
In
contrast to the Firestorm's pivotless frame, the HONDA SP1 had
conventional twin aluminium main spars. The frame used the engine as
a stressed member, and mounted its rear shock on a large aluminium
lower cross-member. Front forks were upside-down 43mm units and, like
the rear shock, were multi-adjustable.
Compact
and eager to rev
The
HONDA SP1 was compact, its clip-ons low. footrests high, and seat thinly
padded. The finish was basic by Honda standards, with unlacquered
stickers, and wiring visible inside the tairing. Equally racy was the
tall first gear, good for 70mph (113km/h).
But
the motor's flexibility helped make the bike fast and easy to ride.
And the engine loved to rev, rocketing towards the lO,OOOrpm redline
with such enthusiasm that the rider's left foot had to flick rapidly
through the gearbox, as the bike headed for a top speed of 165mph
(266km/h).

The
SP-1 was not particularly light, at 4311b (196kg), but it handled
very well. Its rigid twin- spar frame combined with high-quality
cycle parts to make for precise control. Suspension at both ends was
firm, ideal for racetrack or smooth road (though harsh on a bumpy
one). And the front brake set-up of large twin discs and four-piston
Nissin calipers gave real bite plus just the right amount of feel.
There was
no doubt that the HONDA SP1 had been designed primarily for the track, to
recapture Honda's reputation for building the world's fastest
four-stroke motorcycles. Edwards' title in the bike's tirst season
was vindication of Honda's approach. Equally importantly, in
designing the street-legal machine on which the racer was based.
Honda had produced an outstanding roadster that blended the tirm s
traditional sophistication and engineering quality with V-twin feel
and character.
