Yamaha launched the Yamaha YZF-R1 after redesigning the Genesis engine to offset the crankshaft, gearbox input and output shafts. This "compacting" of the engine yielded a huge dividend in that the total engine length was now much shorter. This allowed the wheelbase to be shortened significantly which resulted in much quicker handling and an optimized center of gravity. The bike had a compression ratio of 11.8:1 with a 6-speed multi-plate clutch transmission.
