Genuine Shoulder Bolt M8x1.25x21 for Royal Enfield Classic 350 Reborn / Meteor 350 / Hunter 350 / Bullet 350 | 1100263/E

If your front-end hardware has started loosening, rusting, or the bolt head is rounding off during service, don’t risk a “local bolt” on a safety-critical area. Royal Enfield 1100263/E is a genuine OEM shouldered bolt (M8 x 1.25 x 21) designed for precise fit and correct shoulder seating—important wherever alignment matters in the front wheel assembly (as listed in parts books for the new-generation 350 range). 

Compared to generic aftermarket bolts, the OEM shoulder profile helps maintain proper component alignment and consistent torque feel during installation—reducing chances of play, uneven clamping, or repeat loosening after rides. This is the right choice for owners who want factory-spec maintenance, clean fitment, and fewer comeback issues.

Tip: Always match by part number 1100263/E (sometimes shown as 1100263 on dealer sites) and torque as per service manual for your model/assembly.

FAQs 

1. Is 1100263/E a genuine Royal Enfield bolt?
   Yes—this part number is listed as a genuine RE bolt by multiple sellers, and matches the OEM naming/spec “BOLT, M8 x 1.25 x 21, SHOULDERED.” 

2. Where is this bolt used?
   It appears in front wheel parts-book pages for the J-platform 350 motorcycles. Exact placement can vary by assembly; match by part number in your diagram before ordering. 

3. Can I use a local hardware bolt instead?
   Not recommended. The OEM shouldered profile is designed for correct seating/alignment; a regular bolt may clamp differently and can increase play/loosening risk over time. 

4. Does “/E” matter? I sometimes see 1100263 without suffix.
   Many listings show it as 1100263 while the formal RE format may show 1100263/E. Match the spec and part number family before purchase.
