This kit uses a forged high-silicon aluminum alloy piston designed for strength, durability, longevity, and increased horsepower. Its innovative forging design and piston skirt support increased horsepower and torque.\u003c\/p\u003e\u003cp\u003eThe kit features a forged piston, rings, wrist pin, and circlips. High-compression piston designs, ultra-stiff strutted forgings, and titanium nitride-coated rings are intended to support sustained power. Each piston is E-Coated on the crown, ring grooves, and pin bore for increased wear resistance and protection from micro-welding, galling, and detonation. GP Series parts generally have less machining on the outside to help seal the bore for increased compression. Boost ports are removed for a more predictable powerband and increased pull on the top end.\u003c\/p\u003e\u003cp\u003eThis WISECO piston kit has distributor part number 653M04150 and manufacturer part number 653M04150. It fits the 1982, 1983, 1986, 1996, 2000, 2004, 2015, 2019, 2025, and 2026 Yamaha PW50. Cylinder sleeves must be purchased separately.
