The 15x1.2 piston axle circlips are essential elements that maintain the piston in place on its axis. Due to the mechanical stresses they undergo, it is imperative to replace them with each change of piston. This replacement is strongly recommended by karting professionals to avoid any risk of motor case.

Detailed description:

The 15x1.2 piston axle circlips provide secure fastening of the piston on its axis, thus preventing any lateral displacement that can damage the engine. Despite their small size, these components undergo vibrations and high stresses, which can weaken them over time.

A used or misapproved circlip can come off, resulting in irreversible internal damage. This is why it is strongly recommended by Karting experts systematically replace it with each piston change. This simple but essential precaution helps preserve the performance and longevity of the engine.
