PISTON KIT 92-98 YZ250 68.00 C, WOSSNER 8023DC YAMAHA MX
Wossner forged piston kit for Yamaha YZ250 and WR250 models. Features +0.02mm oversize bore size of 68.02mm, with an actual diameter of 67.96mm. This piston kit is engineered for enhanced thermal conductivity and mechanical stability. The elliptical piston profile helps maintain an even load distribution during heat expansion, reducing stress concentrations and preventing piston collapse. Its design supports effective combustion heat transfer to the cylinder wall, contributing to improved reliability. Manufactured in Germany. Specifications include a compression height of 36.00mm, stroke of 68.00mm, displacement of 246 cm³, piston clearance of 0.06mm, and a 2-stroke compression ratio. Includes piston kit part number 8023DC, lock CW18, pin WP033, ring set RSB6800 x2, and rod P2029.

FULL DESCRIPTION
Wossner Forged Piston Kit for Yamaha YZ250 & WR250
This Wossner forged piston kit is engineered for enhanced thermal conductivity and mechanical stability. The elliptical piston profile helps maintain an even load distribution during heat expansion, reducing stress concentrations and preventing piston collapse. Its design supports effective combustion heat transfer to the cylinder wall, contributing to improved reliability under demanding conditions.
Key Features
- Forged piston construction ensures high structural integrity.
- Elliptical design provides balanced expansion and bearing surface.
- Reduces localized stress and risk of collapse under thermal load.
- Supports effective heat dissipation from the combustion chamber.
- Precision manufactured in Germany.
