2009 Yamaha R1


Yamaha have anounced the new 2009 R1 to have a crossplane crankshaft, which effectively allows a softer power delivery, aiding traction, tyre life, and ultimately increasing lap times for the professional rider.

The technical design allows for crankpins to be set 90 degrees apart, with a firing interval of 270° - 180° - 90° - 180°. A conventional (screamer) engine uses a constant 180° firing interval.

Yamaha have mentioned that cost has been an issue in the development of the new R1, which has been developed specifically for WSB, and they have also noted that most customers will prefer the seamless power delivery of the traditional engine, however the new bike should raise the stakes in the racing world.

The new R1 was on display at the recent Intermot Show at Cologne in Germany, no mention was made of the weight of the bike. Tom Sykes and Ben Spies will race the new R1 in the 2009 World Superbike Series.
