RCB RS1 17MM LH Forged Brake Pump Carbon 01BP030T

The RCB Forged Master Brake Pump Carbon RS1 17MM (LH) 01BP030T is a high-performance motorcycle braking upgrade designed for riders who demand stronger stopping power, improved brake feel, and premium race-inspired styling. Manufactured by RCB (Racing Boy), a globally recognized motorcycle performance brand, this RS1 Series forged brake master pump is engineered for street riders, enthusiasts, and performance-focused builds seeking superior braking response and durability.

This model features a 17MM piston size, making it suitable for motorcycles that require firmer hydraulic pressure, responsive lever feel, and enhanced braking modulation. The 17MM bore is commonly chosen for upgraded braking systems, larger calipers, and performance setups where consistent pressure and control are important. It delivers confident braking during daily riding, highway speeds, aggressive cornering, and demanding road conditions.

The forged alloy master cylinder body provides significantly higher structural strength compared to many standard cast units. Forging enhances metal density and durability while maintaining a lighter overall weight. This results in better long-term reliability, reduced flex under pressure, and more precise braking performance. RCB markets the forged body for enhanced structural strength and durability.

A premium carbon-style lever adds lightweight performance and aggressive aesthetics. The lever is ergonomically shaped for comfortable finger reach and smoother operation. Many RS1 units also include adjustable reach features for personalized control feel. The left-hand (LH) configuration makes this model suitable for custom hydraulic clutch conversions or left-side braking applications depending on motorcycle setup. Buyers should confirm their specific vehicle requirements before installation.

This brake pump includes an external fluid reservoir system for convenient brake fluid level inspection and easier maintenance. Some sellers list compatibility with brake fluids up to DOT5, but users should always verify fluid specifications directly from manufacturer guidance for their exact application.

Finished with RCB’s signature premium styling, the RS1 Carbon 17MM master pump is ideal for custom motorcycles, naked bikes, scooters, underbone bikes, track-inspired builds, and performance street machines. Whether you are upgrading from a stock brake pump or building a custom brake system, this product offers stronger braking confidence, improved lever feedback, and standout visual appeal.

Professional installation and brake bleeding are strongly recommended. Always verify banjo fitting angle, hose compatibility, switch integration, lever clearance, and piston sizing with your brake caliper setup before purchase.
