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

Crossplane technology, first pioneered in MotoGP® racing with the M1, puts each piston 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. This uneven order does an amazing thing… it actually lets power build more smoothly. That means smooth roll-on delivery out of the corners, with outstanding tractability, followed by very strong high rpm power. It’s a feeling that’s simply unmatched, like having two engines in one: the low-rpm torquey feel of a twin with the...
