RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
Recommended Additional Upgrades
RCB E2 Enhanced Axial Performance Master Brake Pump – Black is a high-grade, everyday performance control unit engineered to significantly upgrade your vehicle’s factory braking responsiveness. Moving away from standard OEM cast cylinders, the E2 Enhanced series relies on an optimized axial hydraulic path and enlarged chamber mapping to deliver a crisper brake lever feel, reduced mechanical play, and more predictable stopping power.
Finished in a premium matte black coat, this master cylinder balances a sleek look with reliable performance—making it a favorite choice for street sportbikes, underbone commuters, and automatic scooters looking to sharpen their everyday braking habits.
Key Features
-
Enhanced Axial Hydraulic Mapping: Features a refined internal fluid layout that maximizes line pressure from standard handlebar geometry. This delivers a much firmer lever feel and faster brake pad engagement compared to stock setups.
-
14mm Mirror-Bored Cylinder Piston: Outfitted with a precision-ground 14mm internal piston bore. This dimension displaces the optimal volume of hydraulic fluid required to drive single-piston, dual-piston (such as the RCB S3 Series), or floating caliper systems without causing a stiff or woody lever stroke.
-
Integrated Tinted Fluid Reservoir: Built with an integrated, top-mounted clear smoke-tinted fluid reservoir tank. This clean design eliminates the need for external mounting brackets and loose feed tubes, while letting you check your fluid levels instantly through the outer window.
-
Cast Aluminum Structural Strength: The main master pump shell is cast from a dense aluminum alloy and precision-machined to eliminate structural wall flex under sudden, hard emergency braking conditions.
-
Ergonomically Contoured Black Handlever: The master cylinder includes a matching black lever blade sculpted with smooth, rounded edge lines to distribute finger pressure evenly, lowering hand fatigue during heavy city stop-and-go commuting.

Mechanical Matching Advice: RCB E2 14mm axial configuration is a highly versatile option for stock replacement projects. For the absolute best braking feedback, pair this black master cylinder with high-purity braided stainless steel brake lines. These lines prevent line expansion under pressure, delivering a crisp connection between your fingers and the brake pad.
