WISECO - 871M08950 - Piston Kit - 89.50 mm - Honda
A piston that fits loose burns oil and loses compression. One that fits tight seizes under heat.

Designed and built for each specific 2-stroke powersports engine. Forged from high-silicon alloy for maximum strength and dependability. Piston Diameter: 89.42 mm. Every serious rebuild deserves components engineered to this standard, and the 871M08950 delivers it.
