Maximize the performance and reliability of your classic Honda big-bore two-stroke with the Wossner Single Ring Forged Piston Kit (Part No. 0910-6645 / Mfr. Part No. 8229DA). Engineered to an 88.92 mm standard-bore size, Wossner pistons are forged in-house using high-grade German alloy steel and aluminum, providing exceptional structural integrity, minimal thermal expansion, and superior resistance to scuffing under extreme combustion pressures.
Designed with integrated exhaust oil holes for enhanced lubrication and cooling, this kit ensures smooth, dependable power delivery throughout the RPM range. Single ring design reduces friction losses, reciprocating mass which will increase throttle response and make the most of other port work/ head mods you may have!

TSO Tip
