Royal Enfield RAB00025/A – Front ABS Brake Hose Assembly (ABS Module to Front Master Cylinder) for Classic 500 & Bullet 500 EFI (ABS Models Only)

The Royal Enfield RAB00025/A Front ABS Brake Hose Assembly connects the ABS modulator to the front brake master cylinder on late-model 500cc UCE EFI Royal Enfield motorcycles with ABS. This is a genuine OEM Royal Enfield hydraulic hose, not a local aftermarket replacement, which means correct length, routing, bend angles and fittings exactly as per factory microfiche and ABS calibration.

On ABS-equipped Classic 500 and Bullet 500 EFI / Trials 500, this hose is a critical safety component that carries brake fluid under high pressure from the master cylinder into the ABS module. Over time, hoses can age, crack, or swell internally, leading to a spongy lever feel, delayed braking response, or visible weeping at the crimped ends. Replacing the hose with the correct part number RAB00025/A restores factory braking performance and ensures the ABS can modulate pressure accurately during hard braking or wet conditions.

This assembly comes ready to install with factory-crimped fittings. Pair it with fresh DOT 3/4 brake fluid and a proper bleed to get the best results. Ideal for:

• Owners restoring or maintaining Classic 500 / Bullet 500 ABS

• Workshops wanting zero-guesswork, catalog-correct fitment

• Riders replacing damaged or rusted OEM hoses after a fall or fork swap

Note: Some online sellers loosely advertise this hose for 350 models as well. We only list confirmed 500cc ABS models below; for any other bike, match the part number on your original hose or confirm with your RE dealer before ordering.

FAQs 

Q1. Is RAB00025/A compatible with my Classic 350 or Bullet 350 ABS?
A: Compatibility with 350 ABS models is not fully confirmed. Some sellers advertise it for Bullet 350 / Classic 350, but official documentation is unclear. We currently list this hose only for ABS-equipped 500cc UCE models (Classic 500, Bullet 500, Bullet Trials 500). Please confirm with your dealer or by checking the part number on your existing hose before ordering.

Q2. What exactly does this hose do in the braking system?
A: This hose carries high-pressure brake fluid between the front brake master cylinder and the ABS modulator unit. It is critical for ABS to sense and modulate pressure accurately during hard or emergency braking.

Q3. Can I use aftermarket braided hoses instead of this OEM part?
A: Braided hoses are available in the market, but using non-OEM hoses can alter length, routing, and flexibility and may affect ABS performance if not designed specifically for your bike. RAB00025/A is the exact OEM-spec hose recommended when you want factory braking feel and guaranteed fitment.

Q4. Do I get any fittings or washers with this hose?
A: This part number is for the hose assembly only with crimped ends. Banjo bolts and copper washers are usually separate part numbers in the microfiche. We recommend replacing copper washers whenever you open the hydraulic circuit.

Q5. Do I need to bleed the brakes after installing this hose?
A: Yes. Any time you replace a brake hose, you must bleed the front brake system thoroughly (including the ABS module if required by the service manual) using fresh DOT 3 / DOT 4 brake fluid. If unsure, get the job done at a professional workshop.
