Product description

The piston is made of a robust aluminum alloy and is manufactured using a casting process. The moly coating on the piston skirt reduces friction between the piston and cylinder liner, contributing to improved mileage and longer engine life. The oversize of +1.50 mm allows adjustment for machined cylinders.

In addition to the piston, the kit also contains the matching piston rings, which ensure optimal sealing in the combustion chamber. The compression ratio is standard, so no modifications to the engine are required. Precise manufacturing ensures easy assembly and reliable operation.

This piston kit is part of the ENGINE GROUP and belongs to the PISTON + RING KITS product category. It is suitable for replacement during maintenance work or an engine overhaul of the Yamaha RD 350 Ypvs with 2-stroke engine.
