Description

"In the category of Pistons and Piston Kits, Pistons"

The piston in a motorcycle engine is a cylindrical component that moves up and down within the engine's cylinder. It plays a crucial role in the combustion process by transferring the force generated from burning fuel-air mixtures to the crankshaft, which ultimately drives the motorcycle.

Typically made from high-strength materials like aluminum or steel, pistons are designed to withstand high temperatures and pressures.

For KS125-24 models please check your original cylinder bore diameter before purchasing this piston. If you are unsure please contact our customer service department.
