Sherco 300 SEF-R Racing [2016-2017] - Forged pistons

PROX forged pistons for Sherco 300 SEF-R Racing

The PROX forged piston is intended for the 2016-2017 Sherco 300 SEF-R Racing. Its forged aluminum design and standard compression are based on the series-production design of the engine.

Design and function

The piston is made from a specific aluminum alloy. This design reduces friction and supports reliable function during engine operation. The flat crown with a hollow area and four valve pockets reproduce the specified piston shape for the 4T engine.

Vehicle assignment

Suitable for the Sherco 300 SEF-R Racing, built between 2016 and 2017. The specified diameter of 83.97 mm, the oversize +0.02 and the letter C should be compared with the dimensions and design of the existing engine before selection.

Selection note

The standard compression makes this forged piston the right choice if the stock compression design is to be retained. The vehicle model, year of manufacture, piston diameter and the specified piston shape are particularly important for the assignment.
