NISSIN Rear Master Cylinder for Motocross — Ref. MCB-9MX-R
Specifically designed for MX competition, this NISSIN rear master cylinder meets the terrain demands of riders. On muddy and rocky tracks, the small traditional oil gauge window proves vulnerable to debris: cracks, fluid loss, and forced stops. NISSIN offers here a version without a sight window, designed to limit sources of breakage and leaks on race machines.
Sturdy and understated, it features an aluminum finish that complements racing equipment. Ideal for teams and riders looking for a reliable rear component, with a focus on durability against stones and frequent lateral impacts in motocross.
