Lightened and Balanced Cranks

APE RaceCranks completely machines the crank counter-weights to remove weight and narrow the profile (sometimes called “knife-edging”.) The oil holes are fluted on certain models to keep more oil at the bearings. The crank is then balanced on a state-of-the-art computerized balancing machine to extremely tight tolerances.

As all racers know, heavy wheels and brakes spinning fast act like gyroscopes, and resist being moved off their axis, such as leaning the bike over for cornering. Same with the crank. The heavier the spinning crank, the more it resists being tilted when cornering. Light cranks not only make more power, but help improve handling.

APE is known world-wide for our race prep on four cylinder plain-bearing crankshafts. The who’s who of racing depend on APE cranks for performance and dependability. Over 28 years experience modifying motorcycle cranks is available for your motorcycle.

APE experts have reworked every kind of four cylinder plain bearing motorcycle crank there is. From the old Honda sohc 750 to the latest GSXR1000.

The advantage of a lightened crank… Much quicker throttle response, less power wasted trying to turn a heavy crank means more power to the rear wheel. The engine accelerates faster. Harder pull off the corners. Reshaped counterweights move through the oil mist with less drag. Lighter cranks have less gyro effect.
