HONDA
FIREBLADE
Honda's
stunningly fast and light I
CBR900RR had taken the superbike world by storm back in 1992,
establishing an unmatched reputation for performance and agile
handling. But although the FireBlade remained very popular through
the 1990s and was updated several times, subsequent models were
notable more for their refinement than for the raw excitement of the
original.
Then,
in 2000, Honda struck back with a much modified new generation
'Blade, known as the CBR929RR in the States. The new machine's vital
statistics alone were enough to prove just how serious Honda was. The
CBR produced I50bhp and weighed just 3751b (170kg), making it 22bhp
more powerful and 221b (10kg) lighter than the previous year's
version - and giving it a small but distinct advantage, at least on
paper, over its arch rival, Yamaha's YZF-R1.
Honda's
engineers, led by 'father of the Honda FireBlade' Tadao Baba, threw
everything at this model, which held a much-modified engine,
enlarged
from 918 to 929cc, in a completely new chassis.
The
liquid-cooled motor's new capacity was achieved by using
shorter-stroke dimensions, which allowed larger valves. Reshaped,
forged pistons, a narrower valve angle and more compact combustion
chamber also contributed to the increased power.
Pivotless
frame design

A
digital fuel-injection system replaced the previous carburettors. The
partly titanium exhaust system incorporated a Yamaha-style valve, and
there were numerous changes in the chassis. Frame design was a
variant of Honda's 'pivotless' layout, designed to permit a
controlled amount of flex near the centre of gravity. For the first
time the RR's front wheel was 17 inches in diameter. Upside- down
forks also made a first appearance.
The
Honda also looked different when viewed from the saddle, thanks to
its slimmer fuel tank plus a new digital speedometer in the cockpit.
More importantly, it was distinctly livelier too. The previous CBR
had been fast and agile, but this bike was in a different league
thanks to its ultra-light weight and added power. It responded to a
sub- 5000rpm tweak of the throttle in top gear by accelerating
crisply and hard, charging smoothly and with no real power step
towards the 11,5()0rpm redline. The 16-valve motor was hugely strong
at the top end, too, sending the CBR storming towards a top speed of
about 170mph (274km/h).
Handling
was magical, thanks to the blend of frame rigidity, excellent
suspension and light weight. The suspension required careful fine-
tuning, but once set up correctly the Honda steered quickly, yet
stayed stable despite the lack of a steering damper. An uprated front
brake combination of four-piston calipers and huge discs supplied
phenomenal stopping power.
Honda's
revisions had not only produced the best honda FireBlade ever, they had put
the CBR right back in contention for the unofficial title of world's
fastest and best sports bike. In many respects the CBR and its YZF-R1
rival were too closely matched to split. For street riding the CBR's
sophistication and reliability record counted in its favour. One
thing was beyond doubt: on road and track, the FireBlade was right
back on the pace.
