Description

A piston kit for a motorcycle typically includes all the essential components needed for piston replacement or upgrade. It generally comprises:

  • Piston: The main component that moves up and down within the cylinder, transferring combustion forces to the crankshaft.
  • Piston Rings: Seals that fit into grooves on the piston to prevent gas leaks and control oil consumption.
  • Piston Pin: Also known as the wrist pin, it connects the piston to the connecting rod.
  • Circlips: Small retaining clips that hold the piston pin in place within the piston.


  • These components are often made from high-strength materials designed to withstand the engine's operating conditions. A piston kit ensures smooth engine operation, proper compression, and efficient performance by providing a complete set of parts for effective piston function and maintenance.
