Product Details

The Wiseco 423M07100 is a high-performance forged piston kit with a 71.00mm bore designed for Kawasaki 750 two-stroke applications. Each kit includes the piston, rings (ring set 2795CD), wrist pin, and circlips — everything needed for a complete top-end rebuild.

Key Features:

  • Forged high-silicon aluminum alloy construction for superior strength, reduced weight, and improved heat transfer
  • 71.00mm bore diameter with a 16mm wrist pin and 32mm compression height
  • 68mm overall piston length with a 24mm wide wrist pin bearing
  • 2-ring design for optimal sealing and performance
  • Complete kit includes piston, rings (2795CD ring set), wrist pin, and circlips
  • Innovative forging design and optimized piston skirt profile engineered to maximize horsepower and torque
  • Forged and machined in the USA using the latest 3D design techniques and finite element modeling software

Important Notes: Oversize pistons require cylinder sleeving. Available in multiple bore sizes (71.00mm, 71.50mm, 72.00mm, 72.50mm, and 73.00mm). Complete weight is approximately 291g (0.64 lbs).

Wiseco is the only aftermarket piston manufacturer in the United States that produces pistons exclusively through the forging process, delivering race-proven durability for demanding two-stroke street and performance applications.

Amazon Payment was easy.

Great price!

Good to go for now.

Very quick and easy. And the price is the lowest I've found. Juse wish it would have stated somewhere that you still have to have the keys reprogrammed.

So Far So Good...Just placed my order and will let you know how it worked out when it gets here Bob

Thanks for the safe guarantee.
