DescriptionProx Forged Piston kit

Product details :

Features

PROX Forged Piston designed for Cross displacements, this forged aluminum piston matches the original dimensions for a close-to-factory reconditioning. Machined from a specific alloy, it aims to limit friction and withstand the high rev demands encountered in motocross.

Manufacturer reference: 01.2417.A
Compression: standard 13.5/1
Diameter: Ø 76.95 mm (oversize letter A)
Material: forged aluminum
Number of segments: Kit (replacement segments: CP1612C)
Universe: Cross

This PROX piston is aimed at riders and workshops looking for a robust replacement part to restore their engine's original performance. Its forged construction promotes good mechanical strength under load while maintaining the necessary dimensions for precise installation. Ideal for top-end operations on off-road motorcycles where resistance to stress and consistency at revs matter.

Common compatibilities: YAMAHA YZ 250 F (CG40 2019 / CG39 2018) and YAMAHA WR 250 F (RE25 2018). Please check the reference and specifications of your model before ordering to ensure proper fit.
