Wiseco 556M06800 Forged Piston Kit 68mm 0.60mm Overbore 2-Stroke Dirt Bike

The Wiseco 556M06800 is a complete forged piston kit designed for the Kawasaki KXF250 Tecate 4 (1987–1988) at a 0.60mm overbore (68.00mm bore diameter). Built using Wiseco's industry-leading in-house forging process, this kit delivers the strength, precision, and durability that demanding off-road and motocross applications require.

What's Included:

• Forged aluminum piston
• Piston rings
• Wrist pin
• Circlips

Key Features:

• 100% forged construction — forged aluminum alloy provides a tighter grain structure, superior tensile strength, and greater resistance to impact and fatigue compared to cast alternatives
• Asymmetrical piston skirt — reduces wear and evenly distributes load on the major thrust side for extended service life
• Precision ring groove with custom lap compression ring for optimized sealing and enhanced power output
• Optimized strength-to-weight ratio — engineered to maximize performance without adding unnecessary mass
• Engineered, forged, and machined in the USA — all forge tooling and manufacturing processes are controlled domestically, from raw bar stock to finished skirt-coated parts
• Designed and built specifically for the 2-stroke Kawasaki KXF250 Tecate 4 engine platform

Wiseco is the only U.S. manufacturer that produces powersports pistons exclusively through the forging process. Unlike brittle cast pistons that can fail catastrophically under stress, Wiseco's forgings feature condensed, aligned grain structure that produces higher mechanical properties and superior fatigue resistance — exactly what high-performance 2-stroke dirt bike engines demand.
