Features

PROX Forged Piston (ref. 01.7415.B) — Designed for engine restoration of motocross machines, this forged aluminum piston features machining dimensions suitable for standard preparations. Its "flat with hollow" design allows for precise adaptation to the combustion chamber profile and original settings.

Diameter (bore): Ø 94.970 mm (oversize letter B)
Compression: standard
Material: forged aluminum
Specificity: flat head with hollow for geometric compatibility
Manufacturer reference: 01.7415.B

This piston is aimed at riders and mechanics looking for a replacement part that conforms to the original equipment specifications for engine refurbishment (bore/grinding and assembly with suitable rings). Its finish and dimensions (oversize B) facilitate identification during replacement on prepared or re-machined blocks.
