Yamaha's Yamaha YZF R1 2009 point in this new engine wasnt just increase power to make the masses happy. Who cares that suzuki, honda, kawasaki gave their customers more power by playing with the stoke yada yada. The crossplane crankshaft was designed to balance out the motor more so that the acceleration and deceleration of the inertial torque of the crankshaft didnt interfere with torque production to the wheel. Now that each cyclinder fire 90 degrees from the other the cranshaft is totally balanced for a completely linear throttle response. I can only imagine how smooth this engine will be compared to past sportbike engines. Hope fully it will be vibration free.Yamaha's point in this new engine wasnt just increase power to make the masses happy.

Hope fully it will be vibration free.It is interesting to see the way the different manufacturers take different paths to address the same issue,i.e midrange power.Suzuki have messed about with the stroke of their thou and yamaha have done the crossplane thing-someone thought it silly in light of how suzuki fixed the problem but I think that just gives more power to the consumer because if the manufascturers all did things the same way then there'd be no point in shopping around as they'd all be pretty much the same bikes. kudos to yamaha,albeit styling could be a little less challenging!previous incarnation was way ahead lookswise
