Whatever the multimillion-dollar factory riders want, it seems they get. And
if any of those changes happen to benefit street riders, well fine--but it's
almost an accident. So it is for 2002: A multitude of tweaks have arrived to
make the '02 RC51 more competitive on the track, but the trickle-down effect is
that the bike is now much improved for puck-wearing plebes.
For '02, Honda chose to tweak the engine a bit, put the entire bike on a
part-by-part diet and significantly revise the suspension, chassis and swingarm.
Down in the engine room, the throttle bodies have been supersized from 54mm to
62mm, and the two injectors feeding each combustion chamber now sport 12
laser-drilled jets, rather than the four little garden hoses of the previous
bike, for a finer spray. The injection and ignition mapping were tweaked, also,
resulting in throttle response that's as smooth and creamy as a nougat filling.
(Don't tell Nicky; he's got a sweet tooth.) The new motor feels same-same in
terms of power output; Honda claims a two-horsepower increase for 128 hp at the
crank--but the low-rev snatchiness is nowhere to be found.
The engine is warmed over, but as Honda's Doug Toland said at the intro, "All
of the 'magic' of this bike is in the chassis." The new Pro Frame looks similar
to last year's and has the same amount of rigidity, but weighs 260 grams less
and is more linear in its absorption of stress thanks in part to the new stamped
engine hangers (previous units were cast). Also new is a steering-damper boss up
by the steering head, but on the stock geometry you'd be hard pressed to make
this bike shake its head on the street or track.
Even though the steering-head angle has been reduced one degree to 23.5
degrees--the steepest of any Honda--the RC51 feels planted at all speeds, even
at 130 mph through Willow Springs' infamous Turn Eight. There you sit, tucked
behind the splendid new windscreen that's 1.2 inches taller than last year's,
sensing no instability from either end of the bike. Of course, the new swingarm
(890 grams lighter) is 16mm longer and aids the stabilization effort.
Right above that sexy new swingarm is a revised shock (115 grams lighter).
It's been repositioned to allow room for aftermarket exhaust systems, but also
had its linkage ratio tweaked (4 percent softer on the bottom, 5 percent softer
on top), even though spring rates are the same. Nine percent more compression
damping has been added along with 11 percent more rebound. Up front similar
tweaks have been applied. The fork (145 grams lighter) is now 9 percent softer
on compression, up 16 percent on rebound, with the same spring rate. Fork travel
has also been increased from 4.7 to 5.1 inches. These changes make the bike feel
plush and controllable--a far cry from the wooden feel of the previous bike. The
suspension is simply awesome now, soaking up midcorner ripples yet never getting
out of line or doing anything untoward.
Steering effort is drastically reduced on the new bike. The RC51 is no 954 in
terms of flickability, but the new bike turns in with an ease and precision
that's head and shoulders above the old bike. Pick your line, shove the bar and
you're there. The previous unit's brakes were fine, but the new four-piston
jobbies are even better. The old brakes were extremely progressive--once
activated you only had to move your finger a smidge to stop the bike. The new
brakes are totally linear and require more lever travel, providing better feel,
easier modulation and more feedback.
Speaking of feedback, the RC51 comes wrapped in a new flavor of Dunlop rubber
named D208. The 208s are quite soft for a street tire, which allows them to heat
up quickly and throw down GP-like grip. Feedback from both the front and rear
was excellent, with excellent straight-line stability and precise steering at
high and low speeds.
Our only complaint (and we think some folks at American Honda's marketing
department will back us up on this) is that the bike looks exactly the same as
last year's. Europe gets a bitchin' white/grey, but we get the same paint job as
before. If you go out and buy the "new" model with all the killer updates, you
want people to know, but it's literally impossible to tell the two bikes apart
from a distance.
