Product Details

The Wiseco ProLite Forged Piston Kit is engineered specifically for Yamaha YZ125 2-stroke motocross engines, delivering a performance-focused balance of strength and weight savings. This complete piston kit features Wiseco's advanced forging process that creates a denser, stronger piston structure compared to cast alternatives, allowing for tighter tolerances and improved reliability under racing conditions.

Key Features:

  • ProLite forged aluminum construction reduces reciprocating weight while maintaining durability
  • ArmorGlide skirt coating reduces friction and wear during break-in and operation
  • Precision CNC-machined crown and ring grooves for optimal combustion sealing
  • Includes piston, rings, wrist pin, and circlips for complete installation
  • Designed to OEM specifications for direct replacement fitment
  • 54.00mm bore size for stock or rebuilt cylinder applications

Wiseco's ProLite series is a popular choice among motocross racers and enthusiasts who demand race-proven performance with the convenience of a complete kit. Each piston is individually inspected and tested to ensure it meets Wiseco's rigorous quality standards for competition use.
