Product Details

The Wiseco 4289M06550 is a high-performance forged 4-stroke ATV piston kit featuring a 65.50mm bore (0.020" oversize) and a 12:1 compression ratio, engineered for Honda ATC200-series applications. Designed, forged, and machined in the USA at Wiseco's facility in Mentor, OH, this piston kit delivers the tight tolerances and superior strength that performance and trail riders demand.

Key Features:

  • Forged high-silicon, low-expansion aluminum construction for superior strength, reduced weight, improved heat transfer, and longer service life
  • 65.50mm bore / 0.020" oversize — ideal for cylinders that have been bored over standard
  • 12:1 compression ratio for improved power output
  • Dedicated forging design optimizes strength-to-weight ratio for performance and durability
  • CNC diamond-turned finish ensures precise sizing with no variation
  • Forged grain structure provides superior resistance to impact and fatigue compared to cast alternatives
  • Kit includes: forged piston, piston rings, wrist pin, and circlips — everything needed for a complete top-end rebuild
  • Only Wiseco replacement ring sets are compatible with Wiseco pistons

Wiseco's 4-stroke forged piston kits are proven across all levels of ATV and off-road riding. Whether you're restoring a vintage Honda three-wheeler or building a higher-performance trail machine, the 4289M06550 provides the reliability and performance Wiseco is known for across more than 80 years of piston manufacturing.
