The YZF1000R was a stop-gap bike from the FZR1000R EXUP to the YZF-R1 and produced from existing parts bins.[4][5][permanent dead link] The Thunderace five-valve four-cylinder engine was derived from the FZR1000R EXUP, and the frame was adapted from the YZF750R.[6] The 5-speed gearbox from the FZR1000R EXUP was also reused. The Genesis engine has undergone some changes aimed at improving mid-range power rather than the maximum output, which remains 145 bhp (108 kW).[3] The rotating mass of crankshaft and pistons have been lightened to improve throttle response, and new carburetors equipped with "Throttle Position Sensors" give the ignition some more data to help control the EXUP valve in the exhaust pipe.[7]
