APE: Lightened and Race Balanced Yamaha Crankshafts

Lightened and Race Balanced Yamaha Crankshafts

APE removes excess weight from your crankshaft and then balances it to race specs. Lightened crankshafts rev much quicker. The recontoured counterweights have less drag spinning through the oil mist, resulting in more power to the wheel. (The crankshaft pictured above has had the counterbalance gear removed – optional.)

The crankshafts have their oil holes modified to deliver more oil to the bearings. Then it is computer-balanced for continued operation to 14,000 RPM. Lighten and dynamically race balance the customer-supplied crankshaft. $295.00 Options include removal of the counterbalancer gear, and crankshaft stroking.
