TRX90

Lithium Ion Battery Kits

Here is a new piston that we have developed for the TRX90. It is a 54mm big bore piston. It is designed for the engine builder to setup for custom big bores and strokers. It is the piston we use in our 125cc kits. The piston is made by Wiseco and has very high compression with large valve pockets for big valve heads.

$225.00
