Royal Enfield Interceptor 650, GT 650, Himalayan 411 & Thunderbird Genuine Banjo Bolt Kit | 594721/A

Genuine Royal Enfield Banjo Bolt Kit – 594721/A

Royal Enfield Part Number: 594721/A
Factory Description: BANJO BOLT KIT – P106W10530

594721/A is a genuine Royal Enfield hydraulic brake banjo bolt service kit used in selected front- and rear-brake assemblies across several Royal Enfield motorcycle families.

A banjo bolt is the hollow brake-fluid fastener used where a hydraulic brake hose connects to a master cylinder or brake caliper. Its internal passage allows brake fluid to flow through the hose fitting while the joint is mechanically secured and sealed.

Buyers may also search for this part as a Royal Enfield brake hose bolt, brake line banjo bolt, disc brake banjo bolt, brake caliper hose bolt, master-cylinder banjo bolt, hydraulic brake bolt or P106W10530 banjo bolt kit.

Important: 594721/A is used at multiple brake-system positions on different motorcycles, but it should only be fitted where the Royal Enfield parts catalogue specifically calls for this part number or a documented superseded reference.

Verified Compatibility

Do Not Treat This as a Universal Royal Enfield Brake Bolt

Royal Enfield has used several different banjo bolts, hose assemblies, washers and brake-system service kits across different generations.

The fact that two motorcycles both use hydraulic disc brakes does not prove that their banjo bolts are interchangeable. This listing therefore guarantees only the applications supported by the Royal Enfield parts-catalogue trail for 594721/A or its documented predecessor numbers.

In particular, this listing does not automatically claim fitment for:

• 2021-on Classic 350 J-series / Reborn
• Meteor 350
• Hunter 350
• Bullet 350 J-series
• Himalayan 450
• Guerrilla 450
• Super Meteor 650
• Shotgun 650
• Classic 650
• Bear 650

Some aftermarket sellers cross-list 594721/A for a much wider range. For a genuine OEM listing, compatibility should instead be based on the exact motorcycle EPC / VIN-specific parts requirement.

Documented Older Part Numbers

Royal Enfield genuine-parts data documents older brake-system references that are replaced by 594721/A.

This cross-reference is particularly useful for owners and workshops working from older Bullet / Classic parts catalogues or older service paperwork.

Where Is a Banjo Bolt Used?

Depending on the motorcycle and the specific Royal Enfield brake diagram, 594721/A may be used at a hydraulic brake-hose connection such as:

• front brake master-cylinder connection,
• front brake caliper connection,
• rear brake master-cylinder connection,
• rear brake caliper / hydraulic hose connection,
• or a model-specific ABS brake-line connection.

The position varies by motorcycle. Do not assume that one quantity or one installation position applies to every compatible model.

Why the Banjo Joint Matters

The brake banjo connection is part of the sealed hydraulic circuit. A correctly specified bolt and sealing arrangement are essential because the joint must retain pressurised brake fluid during braking.

A leaking, damaged, cross-threaded or incorrectly assembled banjo joint can cause brake-fluid loss and reduced braking performance. For this reason, brake hydraulic components should be installed carefully and inspected before the motorcycle is ridden.

What You Receive

• 1 x Genuine Royal Enfield Banjo Bolt Kit
• OEM Part Number: 594721/A
• Reference: P106W10530

Factory-pack note: the exact contents supplied under the genuine Royal Enfield service kit should be confirmed from the physical sealed package. This listing does not invent the quantity or material of sealing washers where that has not been verified from the actual pack.

The brake hose, master cylinder, caliper, ABS unit and surrounding brake assemblies are not included unless separately purchased.

Part Details

650 Twins – Interceptor 650 & Continental GT 650

Royal Enfield's Euro 4 650 Twin ABS parts data directly lists 594721/A in the brake system for both the Interceptor 650 Twin and Continental GT 650.

Because later 650 Twin production can receive updated brake hardware, ABS components and service references, owners of later model years should still match the exact EPC/VIN requirement rather than assuming that every production year uses the same brake-line hardware.

Himalayan 411 – Not Himalayan 450

The verified Himalayan application is the Himalayan 410/411 Euro 4 generation, where 594721/A is listed in both front- and rear-brake master-cylinder/caliper systems.

Himalayan 450 is a completely different motorcycle platform and should not be added to this part's compatibility unless its own current catalogue calls for 594721/A.

Thunderbird 350 / 500

The Thunderbird 350 and Thunderbird 500 catalogue directly uses 594721/A in several hydraulic brake service positions, including:

• front master-cylinder banjo bolt kit,
• front brake-caliper banjo bolt kit,
• and rear master-cylinder brake-system service references.

This makes Thunderbird 350 and Thunderbird 500 among the strongest directly documented applications for this genuine kit.

Classic 500 & Bullet 500 Legacy Applications

Older Classic 500 and Bullet 500 brake diagrams used 560534 – Banjo Bolt, Hose Assembly. Royal Enfield genuine-parts data identifies 594721/A as the replacement for 560534.

Accordingly, 594721/A is suitable for those specific older Classic 500 / Bullet 500 brake positions that originally call for 560534.

This should not be interpreted as proof that every Classic or Bullet generation uses 594721/A.

Installation & Brake-Safety Guidance

• Hydraulic brake work is safety-critical. Professional installation is strongly recommended.
• Confirm the exact banjo-bolt position from the motorcycle's workshop manual or parts diagram before dismantling.
• Prevent dirt, moisture and other contamination from entering the open hydraulic system.
• Inspect the hose banjo eye/fitting and mating sealing faces for damage.
• Use the correct sealing washers specified for the particular brake assembly.
• Do not reuse damaged or deformed sealing components.
• Start the banjo bolt by hand to reduce the risk of cross-threading the master cylinder or caliper body.
• Tighten only to the applicable Royal Enfield workshop torque specification for that motorcycle and position.
• After opening the hydraulic circuit, bleed the brake system using the correct procedure and brake fluid specified for the motorcycle.
• Check carefully for fluid leakage while the brake is pressurised.
• Confirm a firm, correct brake lever/pedal feel before road use.

Never ride the motorcycle if the brake lever/pedal feels abnormal, fluid is leaking, or the brake system contains air.

Before Ordering

Confirm at least one of the following:

1. Your motorcycle's parts catalogue directly lists 594721/A.
2. Your existing service requirement uses P106W10530.
3. Your older parts catalogue lists 560534 or 560568 at a position for which genuine parts data specifies 594721/A as the replacement.

If the motorcycle has aftermarket brake hoses, radial master cylinders, caliper conversions, ABS modifications, extended brake lines or any other non-standard braking hardware, confirm the required banjo thread and sealing arrangement independently before ordering.

Q. Are the sealing washers included?
A. The product is sold under Royal Enfield's factory description “Banjo Bolt Kit.” Exact physical pack contents should be taken from the genuine sealed package; this listing does not invent washer quantity or material without pack-level verification.

Q. Can I install it without bleeding the brake?
A. Opening a hydraulic brake connection can introduce air and release brake fluid. The system must be serviced and bled correctly after hydraulic work, following the motorcycle's workshop procedure.
