Product Details

The Wiseco PK1644 complete top end piston kit is engineered specifically for 2003-2011 KTM 105 SX models with a 52mm bore. This comprehensive rebuild kit provides everything needed to restore or overbore your top end to factory-fresh performance.

Kit Includes:

  • High-performance forged piston designed for durability and heat resistance
  • Precision-matched piston rings for optimal compression and oil control
  • Wrist pin and circlips for secure piston-to-rod connection
  • Complete top end gasket set for proper sealing

Wiseco pistons are forged from aerospace-grade aluminum alloy, offering superior strength-to-weight ratio compared to cast pistons. The 855M series piston features optimized skirt profiles and ring groove geometry to reduce friction and maximize power output. Ideal for routine maintenance, performance rebuilds, or overbore applications on KTM two-stroke youth motocross bikes.
