Product Details

The Wiseco PK1449 is a complete forged piston kit designed for the 2004 Honda CR125R, featuring a 57mm (841M) bore size to support overbore or top-end rebuild applications. Wiseco's ProLite forged pistons are manufactured from aerospace-quality 4032 aluminum alloy, delivering superior strength, reduced weight, and excellent heat resistance compared to cast alternatives — making them a trusted choice for motocross and off-road racing.

Key Features:

  • Forged 4032 aluminum construction for maximum strength-to-weight ratio
  • 57mm bore diameter (Wiseco bore code 841M) for overbore top-end rebuilds
  • Precision-machined to tight tolerances for optimal ring seal and power output
  • Compatible with standard 2004 Honda CR125R cylinder with appropriate overbore
  • Wiseco ArmorGlide skirt coating reduces friction and wear for extended service life

Kit Includes:

  • 1 Forged piston (57mm / 841M)
  • Piston ring set
  • Wrist pin (piston pin)
  • Circlip retainers

Wiseco piston kits are engineered to OEM and beyond specifications, making the PK1449 an ideal solution for restoring or upgrading the top end of your 2004 Honda CR125R two-stroke motocross engine.
