“Ultra Light” Custom Wiseco Piston Kit

Top End bearing

Gasket Kit

The advantage of this kit over the Husqvarna 144 is that it uses our “ultra light” Custom Wiseco piston kit. Our 57mm 139 piston is made to our specs and is 37 grams lighter than the stock 125 piston and over 50 grams lighter that the OEM 144 piston. That’s just a hair under 30% less weight!

Max Power’s Custom built Wiseco flat top, 2-ring piston allows the engine to rev faster and pull out longer on top. It also makes vibration nonexistent.

Torque of the 139 is comparable to the 144 but the peak power is more. We feel that the 139 is a good balance of torque and rev that we like better than the 144.

This is the price to modify your parts. If you wish to purchase cores so you do not have to send anything please call or e-mail us.
