The WISECO pison offers great strength with light weight thanks to it’s forged design. And has a Zylan coated skirt for low friction.

This piston is a direct replacement for the ‘stock’ piston included in the TYGA 300cc big bore kit and gives greater scope for performance modifcation.

We offer this piston in two styles. Either shortened on the front side for the standard NSR250 crankcases, or full length for use in modified cases. Please add your choice of style to the comment box during checkout.

By default we will supply the shortened pistons.

Please contact us for instructions on modifying the cases for using full length skirted pistons
