The 2004 Honda CBR1000RR features what Honda calls DSFI (Dual Stage Fuel Injection) with two injectors per cylinder.



The 998cc sportbike has a bore and stroke of 75mm x 56.5mm and a compression ratio of 11.9:1. It has a six-speed cassette type transmission, which Honda press materials says “is easily accessible for rapid gear ratio changes and maintenance at racetrack,” just in time for AMA Superbike rules that don’t allow that type of tranmission changes anymore.



It carries a 120/70-17 front tire and a 190/50-17 rear tire and has a 55.6-inch wheelbase.

The bike has a rotary steering damper with an electronically controlled pressure relief valve, providing less damping at slower road speeds and more damping at higher road speeds.

Like the CBR600RR, the CBR1000RR has Honda’s Unit Pro Link rear suspension layout. Unlike the smaller CBR, the CBR1000RR has radial front brake calipers, with 310mm discs.

The new bike also has undertail mufflers, and comes with a “centrally mounted…fuel tank is positioned low in the frame, increasing mass centralization…”

In what may be a telling sign, Honda press materials released today do not include a claimed dry weight.
