PST006 Description Piston 156FMI 157FMI

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.

PSTR006 Description Piston Rings 156FMI 157FMI

Piston rings are critical components in a motorcycle engine, located on the outer surface of the piston. They serve several key functions:

  • Sealing: Piston rings create a seal between the piston and the cylinder wall, preventing the escape of combustion gases into the crankcase and ensuring efficient power generation.
  • Compression: By sealing the combustion chamber, piston rings help maintain the necessary compression pressure for engine performance.
  • Oil Control: They manage the oil flow between the piston and cylinder wall, ensuring that the correct amount of oil is present for lubrication and reducing oil consumption and emissions.


  • Typically made from high-strength materials like cast iron or steel, piston rings are designed to withstand high temperatures and pressures. Proper maintenance and timely replacement of piston rings are essential for maintaining engine performance, efficiency, and longevity.
