Product description

The piston set includes all the necessary components for replacing the piston in the engine of the Yamaha RD 350 Ypvs. The aluminum alloy ensures low weight and high strength at the same time. The moly coating on the piston skirt reduces friction and wear, which supports engine life.

The oversize of +2.50 mm allows precise adjustment for oversized holes, ensuring optimal fit. The compression ratio is standard, so no changes to the engine management are required.

The kit is designed for use in 2-stroke engines and, in addition to the piston, also contains the appropriate piston rings. This makes replacement easier and ensures that all parts are optimally coordinated with each other.

Using the piston kit helps restore engine performance and supports the reliable function of the drive unit. It is suitable for repairs and maintenance where piston overhaul is required.
