§ 02 / About this part
What it is
The PROX MASTER CYL REBUILD CLTCH, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
The hydraulic clutch on the Honda CRF 450 R and 450 RX runs a sealed master cylinder, and those seals harden and weep with hours. This ProX kit returns the bore to standard: piston, return spring and the full seal set. Fitting it cures the slow lever creep and pressure loss that comes from a tired cylinder. The piston is sized to the original bore, so no shimming or guesswork. Flush the housing with brake cleaner, lubricate the new seals with fresh fluid before insertion, then bleed the line through. A routine service item on a hard-used four-stroke.
