Wiseco 2309M06650 Pro-Lite Piston Kit Forged High-Silicon Aluminum .020 Oversize

The Wiseco 2309M06650 Pro-Lite Piston Kit is a high-performance forged piston solution engineered for riders and builders who demand strength and reliability. This kit includes a .020 oversize (66.50mm bore) piston forged from high-silicon aluminum alloy, delivering an outstanding strength-to-weight ratio ideal for performance and racing applications.

Wiseco's innovative forging process and precision-engineered piston skirt geometry are designed to maximize horsepower and torque output while reducing friction and improving durability over the long term. The Pro-Lite design keeps reciprocating mass low, contributing to faster throttle response and improved engine efficiency.

Kit Includes:

• Forged high-silicon aluminum piston (.020 oversize / 66.50mm)
• Piston rings
• Wrist pin
• Circlips

Key Features:

• Forged construction — superior strength and durability vs. cast pistons
• High-silicon aluminum alloy — excellent thermal expansion control and wear resistance
• Optimized skirt design — reduces friction and increases power output
• Pro-Lite profile — reduced reciprocating weight for improved engine response
• Oversize bore — requires cylinder boring or sleeving to proper spec before installation

Note: Oversize pistons require professional cylinder boring or sleeving to the appropriate dimension prior to installation.
