Keenso 39 mm piston kit for GY6 engine – piston, rings, pin

Keenso 39 mm piston kit for GY6 engine

The motorcycle piston and crank assembly is one of the most heavily loaded groups in an engine, so a worn piston or cracked piston rings noticeably reduce power and increase oil consumption. This installation kit is a complete set of parts for repairing this assembly in horizontal GY6 engines, fitted in many scooters, mopeds and light motorcycles.

What the kit contains

The set includes a piston with a diameter of 39 mm, a set of piston rings, a piston pin and clips that retain the pin in the piston. Such a kit lets you replace the whole piston assembly at once instead of buying individual parts separately, which makes planning an engine overhaul easier.

Material and applications

The piston is made of special spring steel with increased resistance to long-term thermal and mechanical loads inside the cylinder. The kit fits most horizontal GY6 engines used in scooters, quads (ATVs), mopeds and light motorcycles – before buying, compare your engine's cylinder bore with the stated value of 39 mm.
