PROX Forged Piston (ref. 01.7351.A) — Designed for the 350 cm3 displacement in cross/enduro use, this forged aluminium piston meets the requirements of 4-stroke engines. Its construction from a specific alloy and forged machining provides a robust structure, suitable for demanding revs while remaining compatible with original use.
Ideal for an equivalent replacement of the original part, this piston fits the engines of BETA RR 350 4T (Enduro / Racing) models from the years 2013, 2014, and 2019. The surface treatment helps to reduce wear and friction losses, while the oversize A allows for anticipating the condition of the displacement during a re-boring.
Recommended revision: check the condition of the cylinder, adhere to the manufacturer's dimensions and torque specifications during installation. For optimal longevity, have the part fitted by a professional if you are not equipped for engine machining.
