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 counterbalance gear removed - optional.) The crankshafts have the oil holes modified to provide more oil to the bearing. Then it is computer balanced for continued operation to 14,000 RPM. Lighten and balance customer supplied crankshaft. $285.00 Options include removal of the counterbalancer gear, and crankshaft stroking.

GSXR1000 racers. When you opt for the optional counterbalancer gear removal, we can get your crank as light as the new BMW S1000RRs, one of the secrets to it's brutal acceleration

ALUMINUM CYLINDER SPACERS

For the older oil-cooled GSXRs

In some stroker applications, the increased stroke can be compensated for by using a spacer plate. The thickness of the stroker plate you need is exactly 1/2 of your crankshaft's incresed stroke. A crank that has been stroked +.160 would use a .080 spacer plate, etc.

APE's aluminum spacer plates for GSXR come in the following sizes:
