RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
Recommended Additional Upgrades
RCB E2 Plus (E2+) Master Brake Pump with Adjustable Lever is an upgraded, street-performance control unit designed to bring precise hydraulic modulation and custom ergonomics to your everyday ride. Improving on the standard RCB E2 series, the E2+ merges a space-saving axial master cylinder housing with a premium, multi-position adjustable lever blade.
Finished in a highly durable anodized coating, this assembly is the perfect solution for riders looking to eliminate the spongy, vague feel of factory components on underbones, scooters, and lightweight sportbikes.
Key Features
Integrated Multi-Position Span Adjuster: Equipped with an ergonomic dial adjuster mechanism on the face of the lever handle. This allows you to fine-tune the initial distance between the lever blade and your handlebar grip down to the exact millimeter, catering perfectly to varying hand sizes.
14mm Mirror-Bored Cylinder Piston: Outfitted with a precision-ground 14mm internal piston bore. This size moves the optimal volume of hydraulic fluid required to drive single-piston, dual-piston (like the RCB S3 Series), or floating caliper systems without creating a stiff, wooden lever feel.
Anti-Snapping Folding Hinge Joint: Built with an articulating structural pivot that allows the lever blade to flex upward in the event of a stationary drop or tip-over. This drastically minimizes the risk of snapping the lever blade off entirely, leaving your controls operational.
Compact Integrated Fluid Reservoir: Features a clean, top-mounted integrated fluid tank. This self-contained layout eliminates external mounting brackets and loose feed hoses, keeping your handlebar cockpit compact while offering a clear sight window for instant fluid level checks.
Premium Cast & CNC-Machined Alloy: The master housing is cast from high-strength aluminum alloy and CNC-milled at key stress points to reduce body flex and mechanical play under heavy emergency braking loads.
