A master brake pump is one of the most important parts of a hydraulic control system. It converts hand lever pressure into hydraulic force, allowing brake calipers or hydraulic clutch mechanisms to operate efficiently. The RCB 12.7MM LH pump is designed to offer improved modulation, smoother control feel, and dependable response during regular riding, stop-start traffic, touring, or performance-oriented use.
This model features a 12.7MM piston bore, a commonly preferred size for motorcycles requiring balanced lever travel and controllable hydraulic pressure. It offers a combination of responsive actuation and comfortable lever movement, making it suitable for many rider preferences. The piston and seal system is designed for stable fluid pressure and consistent operation under repeated use.
The left-hand (LH) configuration makes this unit suitable for motorcycles or custom setups where a hydraulic control pump is required on the left side of the handlebar. Depending on the motorcycle application, it may be used for left-hand rear brake conversions, hydraulic clutch systems, or specific custom control arrangements. Buyers should always verify intended use and compatibility before purchase.
Constructed from durable aluminium alloy with quality internal components, this master pump is built to resist corrosion, vibration, and regular wear. The lightweight construction helps minimize excess handlebar weight while maintaining strength and durability. The sleek RCB styling adds a modern premium look to the motorcycle cockpit.
The ergonomic lever is designed for rider comfort and easy operation. It provides improved finger grip and smoother actuation, especially useful in city traffic or long rides requiring repeated lever use. Combined with reliable hydraulic performance, it helps improve rider confidence and control.
This product is suitable for street motorcycles, scooters, underbone bikes, naked bikes, custom builds, and upgraded machines using compatible mounting systems. It is ideal as a replacement for worn OEM pumps or as a performance-inspired aftermarket upgrade.
Professional installation is highly recommended. Correct hose fitting, banjo bolt alignment, fluid compatibility, lever clearance, and proper system bleeding are essential for safe operation.
Upgrade your motorcycle control system with the RCB Master Brake Pump 12.7MM LH 01BP017B for dependable hydraulic performance, stylish design, and trusted RCB quality.
