Wiseco PK1407 Pro-Lite 2-Stroke Piston Kit 64.00mm Bore KTM 200SX 2003-2006

The Wiseco PK1407 is a Pro-Lite forged 2-stroke piston kit designed for the KTM 200SX (2003–2006), featuring a 64.00mm bore (SKU: 825M06400). Built to handle the rigors of high-performance off-road and motocross riding, this kit delivers the durability, precision, and power that serious riders demand.

Wiseco's Pro-Lite series represents decades of 2-stroke piston engineering expertise. Every piston is forged in-house in the USA using aerospace-grade alloys, allowing complete control over the manufacturing process — from raw material to finished skirt coating. The result is a piston with superior strength-to-weight ratio that outperforms cast alternatives in demanding race conditions.

Key Features:

• 64.00mm bore — precision forged for standard bore replacement or controlled oversize fitment
• Pro-Lite forged construction — lightweight design delivers faster revs and quicker throttle response
• Innovative piston skirt profile — computer-engineered to minimize cylinder wall friction and maximize power output
• Anti-detonation ring grooves — ring land diameter eliminates ring blow-by while maintaining peak performance
• Aerospace alloy construction — superior strength-to-weight ratio for reduced rotating mass
• ArmorGlide skirt coating — reduces friction and improves break-in durability
• Race-proven design — chosen by top race teams in Supercross, Motocross, and GNCC
• Made in the USA — all forging and tooling produced in-house for consistent quality

Kit Includes:

• One (1) 64.00mm forged piston (SKU: 825M06400)
