The Wiseco 405M06850 Pro-Lite Piston Kit is a complete 2-stroke forged piston kit featuring a 68.50mm bore diameter. Designed for all-purpose 2-stroke riding, this kit delivers a significant upgrade over OEM cast pistons in strength, durability, and throttle response.

Kit Includes:

• Forged Pro-Lite piston
• High-performance piston rings
• Precision alloy wrist pin
• Circlips

Key Features:

• Forged aerospace-grade aluminum alloy construction for a superior strength-to-weight ratio
• CNC-machined for optimal cam shape and profile, delivering peak power and extended service life
• Extra lightening operations reduce reciprocating mass for instant throttle response
• Computer-engineered piston skirt profile minimizes cylinder wall friction
• Anti-detonation grooves and ring land diameter eliminate ring blow-by while maximizing performance
• Horizontal slot-pin oiling reduces friction and provides scuff resistance with a pressure seal groove for maximum ring seal
• Race-proven design trusted by top race teams in Supercross, Motocross, and GNCC competition
• Engineered, forged, and manufactured entirely in the USA

Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons strictly using the forging process, allowing full control of every stage from raw material to finished skirt coating. The Pro-Lite series represents Wiseco's staple 2-stroke forged piston — offering an ideal balance of performance, reliability, and value for both track and trail riding.

Note: Oversize pistons require cylinder sleeving or re-boring. Verify bore size before ordering.
