Wiseco PK1329 Pro-Lite Forged Piston Kit Bore - 2-Stroke 68.00mm

The Wiseco PK1329 Pro-Lite Piston Kit is a complete top-end forged piston solution designed for 2-stroke dirt bike applications. Featuring a 68.00mm (1.00mm overbore) bore diameter with Wiseco's proprietary 642M forging, this kit delivers the strength, durability, and lightweight performance demanded by serious off-road riders.

Pro-Lite Series Features:

• Forged aerospace-grade alloy construction for a superior strength-to-weight ratio over cast alternatives
• Extra-lightweight piston design engineered for instant throttle response and reduced reciprocating mass
• Computer-engineered piston skirt profile minimizes cylinder wall friction for improved efficiency and longevity
• Anti-detonation grooves and precision ring land diameter eliminate ring blow-by and maximize combustion sealing
• Single-ring 2-stroke design reduces weight and friction while increasing power delivery
• Condensed, aligned grain structure provides higher mechanical properties and superior resistance to impact and fatigue versus cast pistons
• Top-end gasket kit included — everything needed to complete a proper rebuild in one package

Wiseco forges all Pro-Lite pistons in-house using proprietary forge tooling, allowing complete quality control from raw bar stock through finished skirt-coated parts. In-house dyno testing and decades of 2-stroke piston development make the Pro-Lite the benchmark forged piston for all-purpose dirt bike riding. Unlike brittle cast pistons that can fail catastrophically under peak stress, Wiseco forgings are engineered to absorb the abuse of high-performance motorsport use.

Kit Includes: Forged piston, piston ring(s), wrist pin, wrist pin clips, and top-end gasket kit.
