Description
Keep your little shredder’s PW50 running at its best with the Namura Performance Piston & Rings Kit – Yamaha PW50 1981–2023. Most OEM manuals recommend replacing pistons and rings every 25–30 hours on small-bore engines, and Namura makes that job easier, stronger, and faster with their high-performance designs.
This isn’t your average piston kit. Namura uses an advanced MOS2 (Teflon/Molybdenum) coated piston skirt—rolled on, not sprayed. That makes the bond ten times stronger, improving heat transfer, reducing friction, and preventing dreaded cold seizures. Translation: smoother power, longer life, and fewer headaches.
The smooth-machined piston head reflects combustion heat instead of absorbing it, keeping things cool under pressure. Dyno testing shows this feature can even bump horsepower and fuel economy by up to 6%. Add in anodized domes (75% stronger than standard pistons) plus the hypereutectic casting process for maximum durability, and you’ve got a piston kit ready to handle serious riding conditions.
Each kit includes everything you need:
✔️ Piston
✔️ Rings
✔️ Wrist pin
✔️ Circlips
No hunting for extra parts, just a complete package that restores your Yamaha PW50’s performance.
⚡ Why riders trust Namura PW50 piston kits:
- Boosts durability and heat resistance
- Helps prevent cold seizures and wear
- Increases performance & fuel efficiency
- Complete kit for an easy rebuild
If your PW50 is losing power, smoking too much, or just due for service, this Namura Piston & Rings Yamaha PW50 1981–2023 kit is the proven choice.
