Product Details

The Wiseco 4156M06550 is a high-performance forged piston designed for dirt bike applications, suitable for both trail riding and competitive racing. Wiseco is one of the most trusted names in aftermarket pistons, and this unit is manufactured to exacting tolerances for a reliable, drop-in fit.

Key Features:

  • Forged high-silicon aluminum alloy construction for superior strength-to-weight ratio and long-term durability
  • Innovative forging design with optimized piston skirt geometry to maximize horsepower and torque output
  • Standard bore sizing for straightforward replacement without the need for overboring the cylinder
  • Complete kit — includes piston, rings, and circlips for a ready-to-install solution
  • Engineered for both trail and racing applications, delivering consistent performance under demanding conditions

Wiseco's forged pistons outperform cast alternatives by offering greater resistance to heat and mechanical stress, making them ideal for high-revving two-stroke dirt bike engines. The included rings and circlips ensure you have everything needed for a complete piston replacement.
