RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
Recommended Additional Upgrades
RCB S1-FL 14mm Forged Alloy Radial Master Brake Pump represents the next evolution in high-performance braking controls from RCB. Building upon the success of the classic S1 series, the S1-FL (Forged / Floating) line introduces an articulating structural design optimized for aggressive street track environments, high-velocity aerodynamics, and extreme crash resilience.
By combining an inline radial mechanical layout with a premium forged chassis, this master pump completely eliminates housing flex, providing crisp initial bite and micro-precise trailing-brake modulation.
Key Features
-
Premium High-Density Forged Shell: Formed via a high-pressure alloy forging process. This maximizes material grain alignment, preventing internal cylinder wall expansion under heavy emergency braking loads for a firm, zero-sponginess lever feel.
-
90° Anti-Breakage Folding Joint: Engineered with a specialized floating pivot joint that allows the lever blade to swing upward up to 90 degrees during an impact. This prevents the blade from snapping or bending during low-sides, track slides, or stationary tip-overs.
-
True Radial Alignment Efficiency: Positions the internal 14mm piston cylinder perfectly inline with your hand’s natural pulling stroke. This layout minimizes internal friction and structural energy losses, transferring 100% of your input force directly into hydraulic line pressure.
-
14mm Precision Piston Bore: Specially dimensioned at 14mm, creating an ideal balance of fluid displacement. This bore diameter is perfectly matched to actuate high-performance single-piston, dual-piston (like the RCB S3), or small 4-piston calipers without requiring excessive lever travel.
-
Aero-Draft Wind-Cutout Vent: The outer tip of the lever blade features an open aerodynamic slot. This cutout allows high-velocity wind currents to pass straight through the blade at track speeds, eliminating unexpected aerodynamic drag from acting on the front brake assembly.
-
Stepless Thumb Wheel Span Adjuster: Features an inline threaded dial adjuster mechanism on the face of the handle. This allows you to fine-tune the starting gap between the blade and your handlebar grip down to the exact millimeter.

FAQs
Is this master cylinder compatible with my motorcycle?
Yes, this master cylinder offers universal fitment and works with most motorcycles, especially 150cc to 350cc bikes with hydraulic brake systems.
Do I have to buy RCB brake hose with this?
Most customers buy the RCB brake hose when they buy the RCB S1 FL Master Brake Pump for better braking performance upgrade, but it is not like you have to buy the brake hose with the master cylinder.
What makes a 14mm master cylinder better?
A 14mm master cylinder provides a balanced braking feel. It gives better control without making the brake too hard or too soft.
Is this master cylinder suitable for daily use?
Yes, it is ideal for daily riding as well as performance use. It improves safety and rider confidence.
Does this include a brake lever?
Yes, it comes with an adjustable brake lever for better comfort and control.
Do I need professional installation?
Installation is simple, but professional installation is recommended for the best performance and safety.
How do I verify the authenticity?
You can scan the authentication QR code included with the product to confirm it is genuine.
