RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
Upgrade your motorcycle’s cockpit controls with the ultimate synchronized performance bundle. The RCB E2 Front Brake Master Cylinder & Clutch Combo Set pairs the redesigned RCB E2 Enhanced Axial Front Brake Pump (14mm) with the perfectly matching RCB E2 Mechanical Cable Clutch Perch.
Engineered for street riders and track enthusiasts alike, this premium pairing completely eliminates mismatched handlebars while delivering crisp hydraulic responsiveness, precise lever feel, and flawless visual symmetry across your bars.
Axial Performance Combo
1. RCB E2 Enhanced Axial Master Brake Pump (14mm)
Built for superior mechanical leverage, this master cylinder features a refined axial piston configuration that delivers optimized fluid displacement for small-to-medium displacement motorcycles.
-
14mm Piston Bore: Moves an increased volume of fluid compared to stock setups, instantly replacing a soft or “mushy” lever response with a firm, highly communicative, and progressive stopping bite.
-
Ergonomic Comfort Lever: The cast aluminum lever blade is carefully contoured to reduce pressure points on your fingers, giving you tireless modulation during heavy city braking or spirited track cornering.
-
Integrated Fluid Reservoir: Features a clean, low-profile internal fluid reservoir tank equipped with a crystal-clear site window for quick visual brake fluid level and condition checks.
-
Built-In Safety Features: Designed with an engineered folding/weak point on the lever tip to prevent snapping the entire master cylinder housing during an accidental tip-over or minor low-side crash.
2. RCB E2 Universal Cable Clutch Perch
Say goodbye to asymmetrical cockpit styling. This mechanical cable clutch assembly is specifically shaped, finished, and counter-balanced to match the E2 front brake pump perfectly.
-
Universal Cable Integration: Completely compatible with a wide selection of cable-actuated clutch motorcycles (naked bikes, sportbikes, underbones, and scooters).
-
Smooth Pivot Tolerances: Manufactured with strict mechanical tolerances at the pivot point to eliminate vertical lever slack, resulting in a smooth, linear clutch pull that minimizes hand fatigue.
-
Glove-Friendly Quick Adjuster: Features a large, knurled cable tension wheel that allows you to make instant, on-the-fly adjustments to your clutch cable freeplay without requiring tools.

Combo Benefits
-
Flawless Visual Symmetry: Installing just an aftermarket front brake pump leaves your handlebar looking unbalanced. This set guarantees identical lever shapes, casting finishes, and ergonomics on both sides of your dashboard.
-
Enhanced Linear Brake Control: The “Enhanced Axial Performance” calibration focuses on progressive stopping power. It allows you to feel the exact point of brake pad bite, preventing sudden tire lockup while increasing stopping confidence.
-
Value-Packed Deal: Purchasing the E2 Brake Pump and the E2 Clutch Perch together in this convenient combo saves you money compared to buying them individually while guaranteeing perfect component matching out of the box.
Installation Guidelines
-
Flush and Bleed (Brake Side): Replacing your front master cylinder introduces air into your lines. Refill the E2 integrated reservoir with premium DOT 4 brake fluid from a freshly unsealed bottle and bleed the system thoroughly until the lever feels rock-solid.
-
Lubricate Your Clutch Cable: Before hooking your existing clutch cable into the new E2 perch, apply a dedicated cable lubricant down the sleeve for an ultra-slick, effortless lever pull.
-
Torque Safely: Tighten the handlebar clamps to standard specifications (typically 8 to 10 Nm). Avoid over-tightening; the clamps should be tight enough to stay put under normal use, but loose enough to rotate slightly during a crash rather than snapping off completely.
