Well it claims this...

Originally pioneered in Yamaha's YZR-M1 MotoGP missile, crossplane technology puts each crank pin 90 degrees from the next, with an uneven firing interval of 270-180-90-180 degrees.

This uneven order does something pretty radical. It actually helps the power build more smoothly. That means smooth-as-silk roll-on delivery out of the corners, with bagsful of torque, followed by very strong, high-rpm power. It's like having two engines in one: the low-rpm, torquey feel of a twin combined with the hyperkinetic, high-rpm power of an inline four. As a 2009 R1 rider, you'll enjoy more linear throttle response with awesome power and traction exiting corners.


Sounds good but the proof will be in the test.
