Necessary to keep your engine running, the 4-Stroke straight crankshaft is crucial to transmission functionality. Connecting many different crankcase components together such as the flywheel, connecting rod, and flyweight, it is responsible for creating torque in the crankcase. The result of this is a rotational movement that ultimately results in transmission output and bike movement. So whether your engine has a damaged shaft or you are completely overhauling your engine, you can trust the 4-Stroke Straight Crankshaft to get you back up and running.
