Royal Enfield 594708/A Clamp Kit Front M/C – Mirror Clamp Bracket for Classic 350, Bullet 350/500, Electra 350 & Thunderbird UCE

The Royal Enfield 594708/A – Clamp Kit Front M/C is the genuine front master cylinder mirror clamp bracket used on multiple UCE disc-brake models such as Classic 350, Classic 500 EFI, Bullet 350 UCE (ES), Bullet 500 UCE, Electra 350 UCE and Thunderbird 350/500.

This small but critical OEM part secures the front brake master cylinder and right-hand mirror to the handlebar. Over time, the original clamp can crack, deform or strip its mirror threads due to falls, overtightening or corrosion. Replacing it with a genuine 594708/A clamp kit restores proper clamping force, keeps your master cylinder firmly located, and prevents the brake lever from rotating on hard braking or over rough roads.

Unlike local fabricated clamps, this kit is dimensionally identical to the factory-fitted part, manufactured to Royal Enfield’s specifications. That means correct alignment, correct offset for the lever, and proper support for the OE mirror stem. Ideal for accident repairs, restoration projects or preventive maintenance on ageing UCE bikes, this kit is a simple, bolt-on replacement that maintains OEM safety, reliability and finish.

Note: This listing is for the 594708/A Clamp Kit Front M/C only. It does not include the full master cylinder assembly or brake lever.

FAQs

Q1. Will this fit my Classic 350 Reborn / new Bullet 350 (J-Series) / Meteor / Hunter?
A: No. Those BS6 J-Series models use a different front master cylinder and clamp design with separate KAB-series part numbers. This 594708/A clamp kit is only for older UCE disc-brake models listed in the compatibility table.

Q2. What exactly is included in the “Clamp Kit Front M/C”?
A: It is the original Royal Enfield clamp kit for the front master cylinder, supplied as a service kit under part number 594708/A. It typically includes the mirror clamp bracket and necessary fasteners as per current OEM packing. Always refer to the actual product photos and OE packet for final contents.

Q3. Do I need to open the brake line or bleed the brakes to replace this clamp?
A: In normal cases, no. The clamp kit mounts externally around the master cylinder body on the handlebar. If you only remove the clamp and refit the new one without disconnecting any brake hoses, bleeding is usually not required. However, work should always be done carefully, and if in doubt, have a qualified mechanic perform the job and check brake feel afterwards.

Q4. My mirror threads are stripped / clamp is cracked. Is this the correct fix?
A: Yes – on the supported UCE models, 594708/A is the correct OEM clamp kit. Replacing the damaged clamp with this genuine part is far safer and cleaner than welding or using non-OEM brackets, which can misalign the master cylinder or fail under load.

Q5. How do I confirm fitment if I’m still not sure?
A: Match three things:

1. Your bike model & engine type (should be UCE, not J-Series).

2. Factory front disc-brake setup.

3. The part number on your original packet or RE parts catalogue: 594708 or 594708/A.
   If any of these do not match, treat the fitment as ❓ and verify with your chassis number on the official Royal Enfield spares portal before buying.
