Complete Top End Rebuild Kit Includes:

• Forged ProLite piston with 69mm bore diameter
• Piston ring set designed for high-performance two-stroke engines
• Wrist pin and circlips for secure installation
• Complete top-end gasket set including overbore head gasket

Key Features:

• ProLite forged piston construction reduces weight while maintaining strength
• Precision-machined ring grooves ensure optimal compression and ring seal
• 69mm overbore size increases engine displacement for enhanced power output
• All necessary components included for complete top-end rebuild or overbore project

Wiseco's ProLite pistons are manufactured using advanced forging techniques that create a stronger, lighter piston compared to cast alternatives. The 69mm bore diameter represents an overbore application that increases displacement from the stock configuration, making this kit ideal for racers and enthusiasts seeking additional power from their YZ250 or WR250 engine.
