Motorcycle Piston Kits

The heart of your engine, no doubt, is the piston. Motorcycle pistons have the most demanding job in a powerplant and the whole shebang depends on them performing. Any imperfections can lead to catastrophic failure, not only of the piston, but of all the components working with it. Today’s motorcycles have extremely sophisticated pistons within compared to the ones in much older bikes. They are made to be as light and strong as possible to be able to handle high rev limits.

There are a few reasons to replace your stock motorcycle pistons. The first, and most obvious, is that they have failed. A worn, scratched, melted, or chipped piston will prevent the bike from operating normally or at all. It can also be a sign of something else gone wrong, so be sure to check out the engine while it is apart. With over-size pistons available, you are able to bore or hone out your damaged cylinder for a smooth surface. Another reason to replace pistons is for better performance. Big bore kits allow you to get more compression and more power and torque. High-end aftermarket pistons are also more tolerable to high heat and stress situations that modified engines produce.
