TRANSMISSION UNDERCUTTING

Undercutting a transmission involves machining angels on the engagement dogs and slots to prevent the transmission from jumping out of gear under load. There are three types of undercuts available from APE

Racecut...
This cut is performed on the side of the dogs that are loaded on acceleration. Recommended for hot street bikes and drag racers, dwarf cars, etc.

Up and down cut....
Both sides of the dog are cut to also prevent jumping out of gear on down shifts. Recommended for road Racing.
