“Ultra Light” Custom Wiseco Piston Kit

Top End bearing

Gasket Set

Spark Plug

The kit is both bore and stroke modifications. It uses a “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!

The lighter flat top piston allows the engine to rev faster and pull out longer on top. It also cuts down on vibration.

Torque of the 151 is awesome compared to the a big bore only engine. However the top end pull is where this package shines. This kit is a pro-type power. Mid and top with lots of over rev. A 125 on steroids.

This is the price to modify your entire engine. We do not offer this kit as parts only. Please send us the whole engine with the kickstarter and shifter.

Due to the design of this engine we cannot offer it with any less than a 100 octane minimum fuel requirement.
