Balancer Shaft

LIGHTENING AND BALANCING -$285.00 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. Options include removal of the counterbalancer gear, and crankshaft stroking. If counterbalance gear is removed, see our special lightweight replacement shaft which allows you to remove the entire heavy counterbalance mechanism from the engine here.

Include an APE work order form when sending your crank to APE.


All strokers from APE are race balanced to less than 1/3 gram. APE is the only source for these micro balanced strokers.

APE Crankshaft Department

APE has been modifying and race prepping motorcycle crankshafts for over 22 years. The most popular service is lightening and race balancing cranks for racing and hot rod street bike use. This service consist of precision machining the crank for weight removal and counterweight reshaping, computer race balancing for extended high RPM use, reworking the oil holes on rod journals for increased oil flow at the bearing, and micro polishing all journals. The balancing department uses the latest state of the art computerized balancer that is capable of measuring dynamic out of balance to .01 of a gram. No other balancing shop can balancer closer than APE.

These APE crankshafts have won championships in virtually all kinds of racing; road racing, drag racing, three quarter midgets, dwarf cars, mini sprints, etc. Every model crank is different and requires a different style of modification.


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. 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 resist being tilted when cornering. Light cranks not only make more power, but help improve handling.

APE performs the complete lightening and balancing to the customers crankshaft. Magnaflux to check for cracks, highly recommended on oil cooled GSXR1100+s and FZR1000+s . Visit the Crankshaft web page for a complete listing of services and prices.
