Description
If you're running a classic Yamaha XT500, TT500, or SR500, factory pistons won't cut it if you're serious about reliability and power. The Wiseco 4764M08700 delivers a noticeable bump in combustion efficiency and throttle response—exactly what these air-cooled singles need to perform consistently, whether you're pushing it on pavement or dirt.
