⚡ At a Glance
- • Braking Performance: Hydraulic structure increases response sensitivity and reduces spongy brake feel
- • Best for: Riders of 50cc-125cc dirt bikes and ATVs needing a direct rear brake replacement
- • Not ideal for: Owners of motorcycles above 125cc or machines needing OEM-specific master cylinders
Hydraulic rear brake master cylinder with integrated transparent reservoir and aircraft-grade aluminium construction. Compatible with 50cc-125cc motorcycles and ATVs when thread size matches M8x1.25 or M10x1.25.
Shorter stopping distance - thanks to hydraulic structure
Hydraulic pump design transmits brake pressure more directly, eliminating the compressible air feel that causes a spongy pedal. A firmer pressure path converts lever force into quicker caliper action.
Up to 15% shorter braking distance is claimed, delivering more confident braking on downhill runs and technical sections.
Quick, no-modification fit - with direct-replacement reservoir and mounting
Direct-replacement layout matches standard mounting points and incorporates common thread sizes, M8x1.25 and M10x1.25, so no machining or adapter is required. Installation is straightforward using basic hand tools.
Expect around a 10-minute DIY install for compatible bikes, avoiding workshop visits and saving on labour costs.
Durable under strain - with aircraft-grade aluminium and oil-resistant seals
Aluminium alloy construction resists corrosion and tolerates elevated temperatures, while oil-resistant rubber seal rings maintain hydraulic integrity over repeated use. A transparent reservoir allows visual oil-level checks to spot issues early.
Three-year durability and corrosion- and heat-resistant components reduce maintenance headaches, making the unit reliable for off-road and daily use.
