Honda CBR1000RR, was the successor to the 2002-03 CBR954RR. While evolving the CBR954RR design, few parts were carried over to the CBR1000RR. The compact 998 cc (60.9 cu in) in-line four was a new design, with different bore and stroke dimensions, race-inspired cassette-type six-speed gearbox, all-new ECU-controlled ram-air system, dual-stage fuel injection, and center-up exhaust with a new computer-controlled butterfly valve.
