Product Details

The Wiseco 40104M09200 high-performance piston kit is engineered for 2009-2013 Yamaha Grizzly 550 ATVs, delivering a 10.25:1 compression ratio for enhanced power and performance. This 92mm piston assembly is forged from high-silicon aluminum alloy, providing exceptional strength and dependability under demanding riding conditions.

Key Features:

  • Forged high-silicon aluminum alloy construction for maximum durability
  • Innovative forging design optimizes horsepower and torque output
  • Advanced piston skirt geometry reduces friction and wear
  • 10.25:1 compression ratio for improved throttle response
  • 92mm bore diameter
  • Complete kit includes piston, rings, wrist pin, and circlips

Wiseco pistons are precision-machined to exact tolerances, ensuring proper ring seal and optimal performance. The high-silicon aluminum alloy resists thermal expansion and maintains dimensional stability under high heat conditions. This complete piston kit provides everything needed for installation. Note that oversize pistons require cylinder sleeving for proper fitment.

It was easy

Their website is intuitive and easy to maneuver.

Quick and easy online shopping and check out. Shipping took long because it had to come from a manufacturer. Also considering the part was small shipping costs seemed high. Everything arrived in order though and part seems just right.
