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.

  • 9:1 compression ratio
  • 87.50mm bore diameter
  • Fits TT500, XT500, SR500

  • OEM-quality precision fit
  • Reduced detonation margin
  • Extended ring life
