Wiseco 405M06700 Pro-Lite 2-Stroke Piston Kit 67mm Standard Bore

The Wiseco 405M06700 is a Pro-Lite forged 2-stroke piston kit with a 67.00mm standard bore designed for the Suzuki PE250 and RM250. Engineered, forged, and machined in the USA at Wiseco's Mentor, OH facility, this piston kit delivers the strength, precision, and reliability that 2-stroke riders and racers demand.

Key Features:

• USA forged construction — forged from high-silicon, low-expansion aluminum alloy for superior tensile strength, reduced weight, and improved heat transfer over cast alternatives
• Dedicated forging design — purpose-built for this specific 2-stroke engine, optimizing strength-to-weight ratio through dedicated forgings and lightening operations
• CNC diamond-turned finish — computer-controlled machining ensures precise sizing with no variation, compatible with cast iron, chrome, Nikasil, and boron composite cylinder bore compositions
• ArmorGlide skirt coating — factory-applied coating reduces friction and simplifies fitment; confirm bore size and install with confidence
• Complete kit — includes piston, ring(s), wrist pin, and circlips — everything needed for a full top-end piston replacement
• Race-proven performance — Wiseco's 2-stroke piston legacy spans over 80 years, with a proven track record across motocross, supercross, and off-road competition

Whether you're rebuilding a vintage dirt bike or refreshing a race machine, the Wiseco 405M06700 piston kit delivers OEM-beating quality with performance-focused engineering. Standard 67.00mm bore; oversize variants available for worn or re-sleeved cylinders.
