Product Details

The Wiseco 4731M09700 is a high-performance forged piston designed for demanding dirt bike and ATV applications. This piston measures 97.00mm (2.00mm oversize) and is engineered specifically for KTM 525XC models (2008-2010) and Polaris Outlaw 525 ATVs (2007-2010).

Key Features:

  • Forged in-house construction for superior strength and durability compared to cast pistons
  • Aligned grain structure provides higher mechanical properties and resistance to impact and fatigue
  • Optimized strength-to-weight ratio for maximum performance
  • 2.00mm oversize bore (97.00mm diameter) for cylinder rebuilds
  • Skirt coating for reduced friction and improved longevity
  • Designed to withstand extreme racing conditions and high-performance applications

Wiseco's forging process ensures each piston has a condensed grain structure that aligns with the part's features, making it significantly tougher and more durable than brittle cast alternatives. When your engine demands the reliability to handle aggressive riding and high-stress conditions, Wiseco's forged pistons deliver the performance you need.
