Description
Your XT500 or TT500 demands a piston engineered for reliability under sustained high RPM and load—factory units wear quickly in demanding riding conditions. The Wiseco 4764M08750 kit delivers a high-silicon alloy construction that resists thermal stress and detonation, paired with a chrome-faced ring design that minimizes blow-by and extends engine life. At 9:1 compression, you’ll gain measurable power gains without sacrificing real-world usability on premium unleaded fuel.
