Product Details

The Wiseco 856M06850 is a high-performance forged piston kit designed for KTM 250SX (2005–2014), 250XC, 250XC-W, and 250EXC (2006–2014) two-stroke engines. With a 68.50mm bore diameter, this piston delivers a precise fit and reliable performance for off-road and motocross applications.

Key Features:

  • Forged high-silicon aluminum alloy construction for exceptional strength, durability, and heat resistance under extreme riding conditions
  • Innovative forging design optimizes piston geometry and skirt profile to maximize horsepower and torque output
  • Complete kit includes piston, rings, wrist pin, and circlips — everything needed for a full top-end rebuild
  • 68.50mm oversize bore — cylinder boring or re-sleeving by a qualified machine shop is required prior to installation
  • Manufactured to tight tolerances for consistent ring seal, reduced blow-by, and extended engine life
  • Designed specifically for KTM 250 two-stroke powerplants used in motocross and cross-country competition

Wiseco is a trusted name in performance pistons, with decades of experience supplying OEM and aftermarket piston solutions for powersports applications. The 856M06850 is engineered to meet the demands of serious off-road riders who require dependable power and long-lasting top-end performance.
