Wiseco 673M05075 2-Stroke Forged Piston Kit 50.75mm 0.75mm Oversize

The Wiseco 673M05075 is a high-performance 2-stroke forged piston kit with a 50.75mm bore — a 0.75mm oversize — designed as a precision replacement for the Suzuki LT80 QuadSport and Kawasaki KFX80. As the only U.S. manufacturer with in-house forging capabilities, Wiseco engineers each piston to exact application-specific tolerances for reliable rebuilds and performance upgrades alike.

Key Features:

• Forged high-silicon aluminum alloy construction for superior strength and long service life
• Aerospace-grade alloy provides an optimal strength-to-weight ratio
• Dedicated application forging — not a generic blank — engineered specifically for this engine platform
• Innovative skirt profile and cam shape optimized for peak horsepower, torque, and extended service life
• CNC machined to tight tolerances for precise fit and sealing
• High-performance ring set included for extended life and sustained power output
• Highest-quality alloy wrist pin — precision ground for consistent, durable performance
• Kit includes: piston, rings, pin, and circlips (unless otherwise noted)

Important: This is a 0.75mm oversize piston (50.75mm bore). Installation requires a professionally bored or sleeved cylinder to match. Always verify cylinder bore size before ordering.
