PROX Forged Piston - Ref. 01.6434.A
Designed for demanding riders, this PROX forged piston is intended for Cross and Roadster machines requiring an oversize A. Machined from aluminum alloy, it offers a finish suitable for the cylinder/ring contact for reliable and consistent engine performance. Its forged design provides a homogeneous metal structure, sought after in parts subjected to racing and enduro conditions.
Ideal for restoring a cylinder bored to +0.25 mm (oversize A), this piston is aimed at riders looking for a robust part suitable for the demands of both off-road and road use. Check the bore and tolerances of your cylinder before installation to maintain proper clearance and sealing.
Compatibility (examples): GAS GAS MC 450 F (2023), KTM 450 SX‑F (2022), HUSQVARNA FS 450 (2022). Please confirm the engine reference and bore size before ordering.
