PROX Forged Piston (Manufacturer part no. 01.6443.C) — Designed for demanding cross and roadster engines, this PROX forged aluminum piston is intended for a rebuild that closely resembles the original equipment. The specific alloy minimizes friction and offers dimensional consistency suitable for long sessions and frequent stresses without claiming unverified performance.
This piston is suitable for setups where machining precision and temperature resistance are required. Its oversize of +0.02 allows for a bore to be redone in accordance with manufacturer tolerances. Ideal for mechanics and riders who are refurbishing an engine block and wish to maintain the original geometry and stroke.
Main compatibilities (examples):
Choose this PROX piston for a controlled rebuild: pistons, rings, and bore settings should be checked and verified by your workshop to ensure a compliant and durable installation.
