This piston is forged from high-silicon aluminum alloy, giving it maximum durability and dependability. The advanced forging design and piston skirt work together to unlock more horsepower and torque, while titanium nitride-coated rings keep friction low and performance high. That means your Yamaha PW50 gets smoother power delivery, longer life, and the kind of pull that leaves stock pistons in the dust.

The WISECO 653M04000 High-Performance Piston Kit Yamaha PW50 includes everything you need for a complete install—piston, rings, wrist pin, and circlips. Each piston is E-Coated on the crown, ring grooves, and pin bore for unmatched wear resistance and protection against galling, detonation, or micro-welding. And thanks to Wiseco’s GP Series design, you’ll enjoy tighter compression and a more predictable, stronger powerband.
