Description

This part fits: Yamaha PW50 (1981-2016) and Yamaha QT50 (1979-1987)

Get better-than-original-part quality with Niche Industries' PW50 Piston Kit.  If you need to rebuild the top end of your Y-Zinger or QT10, this bolt-on ready kit will get the job done right out of the box.

This kit includes a cylinder, cylinder headperformance gasket kit, and a standard-sized cast piston kit, giving you even more performance out of your bike.

Our cylinders are solid cast iron and have a black powder coat to keep that classic Yamaha look and feel. The cylinder head is powder coated cast aluminum and machined to provide standard compression.

Just like the original parts, our cylinders have a 40 mm bore and 39.20 mm stroke, so you'll be restoring your PW50 to its factory specs.

Please note, while our cylinders are factory honed and deburred, we do recommend chamfering prior to installation.

Whether you have a classic QT50, Y-Zinger, PW50, or Yamahopper, this piston kit will fit your moped and rebuild their top end as well.

If your mini bike has lost its ‘get-up-and-go’, and there a troubling knocking sound in the engine, our PW50 will help refresh your bike. 

Our parts are in-stock and ready to ship.  We offer top-notch customer service, fast shipping, secure packaging, quality parts, and knowledgeable staff who are more than happy to help.

All ground shipments are sent FREE within mainland USA . Read more...
