GAS GAS EC 250 [2021-2026] - cast piston

PROX cast piston for GAS GAS EC 250

The PROX cast piston is designed for the GAS GAS EC 250 from the 2021-2026 model year range. As a cast aluminum piston with standard compression, it is suitable for replacing the piston in a 2T engine. The special alloy was developed with the aim of minimizing friction and thereby supporting reliable function.
