The RCB S1 Master Brake Pump 14MM LH Black 01BP012B is a premium hydraulic control component designed for motorcycles requiring a left-hand master cylinder setup. Manufactured by RCB (Racing Boy), a trusted global brand known for producing high-performance motorcycle parts, this S1 Series brake pump combines reliable braking performance, durable construction, and premium styling for riders who want improved control and confidence on the road.
A master brake pump is one of the most important parts of a hydraulic control system. It converts lever input into hydraulic pressure, allowing the braking or hydraulic control mechanism to operate smoothly and effectively. A quality master pump improves lever feel, hydraulic consistency, and rider response during traffic riding, highway cruising, and performance applications. The RCB S1 14MM model is designed to deliver controlled pressure with smooth lever modulation and dependable daily-use performance.
This version features a 14MM piston bore, which is commonly selected for motorcycles requiring a balance between lever travel, pressure output, and controllable response. It offers progressive hydraulic feel, making it suitable for riders who prefer smoother operation with confident actuation. The 14MM setup is widely used for various custom and replacement applications.
The left-hand (LH) configuration is designed for motorcycles or custom builds that require hydraulic operation on the left side of the handlebar. Depending on vehicle setup, it may be used for left-side brake conversions, hydraulic clutch systems, or specialized control arrangements. Buyers should always verify their intended application before purchase.
Built using high-quality aluminium alloy, the brake pump body is lightweight, durable, and resistant to corrosion. The strong construction helps withstand regular use, vibration, and pressure cycles while keeping handlebar weight low. Internal precision components such as the piston and seals are engineered for smooth hydraulic operation and long-term reliability.
The black finish gives the brake pump a clean, aggressive, and modern appearance. It blends perfectly with sport bikes, naked motorcycles, commuter bikes, scooters, and custom builds. The coating also helps resist fading, scratches, and weather exposure.
The ergonomic lever design offers comfortable finger reach and better control during repeated use. This is especially beneficial in city traffic, long rides, or situations requiring frequent lever actuation. Combined with RCB engineering quality, it provides a better riding experience with added confidence.
This product is ideal for replacing worn OEM master pumps or upgrading motorcycles with a more premium aftermarket control component. It suits riders who value braking precision, durability, and attractive styling.
Professional installation is strongly recommended. Correct hose fitting, fluid compatibility, banjo alignment, lever clearance, and complete system bleeding are necessary for safe operation.
Upgrade your motorcycle with the RCB S1 Master Brake Pump 14MM LH Black 01BP012B and enjoy smoother hydraulic control, stylish design, and trusted RCB performance.
