DESCRIPTION:
Yamaha claims its Crossplane crankshaft technology—developed on Valentino Rossi’s YZR-M1 MotoGP racer and making its production debut on the new R1–effectively eliminates inertia torque-induced “noise” at the rear tire. Crossplane crankpins are positioned 90 degrees apart, so a piston arrives at TDC/BDC every 90 degrees, compared to every 180 degrees with a conventional crank. As a result, two pistons maintain high speed as the other two are reversing direction, stabilizing crank speed. Reducing crank speed fluctuations reduces the power shake at the rear contact patch, resulting in smoother power delivery, improved traction and enhanced rideability.
