Features

PROX Forged Piston (manufacturer part number 01.7425.B) designed for 4-stroke Cross engines. Made from aluminum alloy, this forged piston maintains original dimensions for a refurbishment close to the first fit. Its "flat with hollow" geometry provides a flat head surface with a localized hollow to respect the combustion chamber and facilitate installation on the intended cylinders.

  • Compression: standard
  • Diameter: Ø 99.970 mm (size Ø 99.970)
  • Oversize letter: B (oversize)
  • Material: forged aluminum
  • Specificity: flat with hollow — geometry suitable for the relevant displacements
  • Manufacturer reference: 01.7425.B

Ideal for Cross riders looking for a robust and precisely machined piston. Compatible notably with BETA RR 480 4T models (RACING, ENDURO RACING) — check the bore and size B before installation. This product is intended for refurbishment and standard exchange operations: adhere to machining tolerances and manufacturer recommendations during installation.
