Wiseco 511M05450 Pro-Lite Forged Piston Kit 54.50mm +0.50mm Oversize

The Wiseco 511M05450 Pro-Lite Piston Kit is a high-performance forged piston solution designed for dirtbike engines. Machined to a 54.50mm bore diameter (+0.50mm oversize), this kit is engineered to restore or upgrade engine performance with precision-fit components.

Wiseco's Pro-Lite pistons are forged from high-silicon aluminum alloy, delivering superior strength-to-weight ratio compared to cast alternatives. The innovative forging design and optimized piston skirt geometry are engineered to maximize horsepower and torque output across the RPM range.

Kit Includes:

• Forged high-silicon aluminum piston
• Piston rings
• Wrist pin
• Circlips

Key Features:

• Forged high-silicon aluminum alloy construction for maximum strength and durability
• Optimized piston skirt design for reduced friction and improved power delivery
• +0.50mm oversize — requires cylinder boring or sleeving to match
• Complete kit includes rings, pin, and circlips for a straightforward rebuild
• Manufactured to OEM-matching tolerances for reliable fit and performance

As with all oversize pistons, the cylinder must be bored or re-sleeved to the corresponding 54.50mm diameter before installation. This is a complete piston kit suitable for engine rebuilds seeking a return to factory performance or a modest displacement increase.
