Product Details

The Wiseco SK1210 Top End Piston Kit is a complete high-performance rebuild solution designed for Ski-Doo snowmobiles equipped with 503cc Rotax 2-stroke engines. This kit features a 73.50mm bore size, which is 1.50mm oversize from the standard 72mm bore, providing increased displacement to 518cc for improved power output.

Complete Kit Includes:

  • High-performance forged aluminum piston with optimized skirt profile
  • Piston rings engineered specifically for 2-stroke applications
  • Wrist pin and circlips
  • Top-end gasket kit for complete engine sealing

Key Features:

  • Forged from high-silicon aluminum bar stock for superior strength and heat resistance
  • Computer-engineered piston skirt profiles reduce cylinder wall friction
  • Lightweight forging design provides instant throttle response and maximum torque
  • Precision-machined to tight tolerances for optimal performance and reliability
  • Compatible with Ski-Doo Alpine 500, Formula 500 SL, and other 503 Rotax-powered models

Wiseco pistons are forged using advanced manufacturing techniques that result in greater strength and lower expansion at high temperatures compared to cast pistons. This complete top-end rebuild kit provides everything needed for a professional-quality engine refresh, delivering improved performance and extended engine life for your snowmobile.

Note: Wiseco pistons must be fitted only with Wiseco rings. Ring types are not interchangeable between different Wiseco series.

Autoplicity has the best price that I could find and my order was delivered quickly. The toolbox did have some small dents and a couple spots where the paint was chipped off, which have already started to rust, so need to buy some paint to repaint those spots. Other than that, everything was great.

Quick... exactly what i needed
