Wossner Piston Kit 89.42mm Honda CR500R 1985-2001 8229D050
Part Number: 09106643Description
Stock pistons limit your Honda CR500R's potential—they can't withstand the demands of aggressive riding or consistent high-RPM operation. The Wossner 89.42mm Piston Kit delivers the strength and precision you need to push your engine harder while maintaining reliability. With aerospace-grade construction and a complete ring-pin-clip package, you're getting a purpose-built upgrade that transforms throttle response and power delivery without compromise.
This kit addresses the two biggest weaknesses in OEM pistons: friction losses and structural limitations. Wossner's permanent skirt coating reduces piston rock, eliminating that characteristic cold-start clatter while minimizing energy waste. The optimized crown and skirt wall cross-section are forged lighter in non-critical zones but reinforced where it counts—delivering the efficiency of a high-revving racing piston without sacrificing durability.
Installation is straightforward for anyone with basic engine rebuild experience, and the complete kit means no hunting for matching components. Whether you're preparing for competition or simply want your CR500R to perform like it should from the factory, this is the piston upgrade serious riders choose.
