Brian Crower Balanced Can-Am X3 / ROTAX 900 ACE (17-up) EN40 Billet Crankshaft (69.7mm Stroke) BC5930

The BC stock stroke billet cranks, due to the counterweight correct design, do not require any heavy-metal to balance for aftermarket rods & pistons. Made from EN40, features a large radius snout for maximum horsepower capability. All cranks are stress relieved, shot peened, magna flux inspected and nitrided (multi step heat treatment) for ultimate performance. Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential. Requires internal balancing of the crank for operation. Price includes balancing.
