Royal Enfield 143745/2 – Gear Lever (Foot Change Lever) for Bullet Cast Iron 350/500, Electra 4S, Lightning, Machismo – 4-Speed Gearbox

Royal Enfield part 143745/2 is the genuine OEM Gear Lever / Foot Change Lever Assembly for classic 4-speed cast-iron Bullets and early Electra/Lightning/Machismo models. Royal Enfield’s official part list records base part 143745 simply as “GEAR LEVER”, with 143745/2 as the current supersession, keeping the same function and OEM spec.

European OEM portals list 143745/2 – GEAR LEVER as a certified Royal Enfield genuine spare, with 143745 flagged as “see replacement 143745/2,” confirming it as the factory-updated lever number. Specialist sellers such as map 143745-2 / 143745/2 to a very specific group of bikes: Bullet 350 (cast iron Standard & Deluxe), Machismo 350, Campus, Bullet 500 CI, Electra 4S KS & ES, Lightning 500, Lightning 535 & 535 ES, Machismo A350.

This is the right-foot gear change lever for 4-speed gearboxes on cast-iron Bullets (and related models). Over time, the lever can bend, wear at the spline, or get damaged in a fall, causing sloppy shifts or the pedal sitting at an odd angle. Replacing it with genuine 143745/2 gives you the original lever geometry, spline fit, and feel, unlike thin local levers that twist easily.

⚠️ Important: This lever is for older 4-speed cast-iron / early AVL models only. It is not compatible with UCE, J-Series, Thunderbird 5-speed, or modern Classic / Bullet / Himalayan / 650 platforms.

FAQs 

Q1. What is the difference between 143745 and 143745/2?
Royal Enfield’s own pricing and assignment pages show 143745 – GEAR LEVER with replacement part number 143745/2. In practice, 143745/2 is the current/updated production number for the same OEM lever design. If your parts book says 143745, 143745/2 is the correct genuine replacement.

Q2. Will this lever fit my Royal Enfield UCE or J-Series Bullet / Classic?
No. 143745/2 is only for older cast-iron and early AVL models with 4-speed gearboxes. UCE and J-Series bikes use completely different shifter assemblies and part numbers. Always match against your model’s microfiche before ordering.

Q3. Is this the right-side gear lever used on old RH-shift Bullets?
Yes – Eurobrit lists 143745 as “RH gear change lever” for early Iron Barrel Classics with right-hand change and 4-speed gearbox. On some later models with left-hand shift linkage, the same lever is used in the pedal assembly. If your original lever cross-refers to 143745 or 143745/2, this is the correct replacement.

Q4. What else should I replace along with the gear lever?
At minimum, inspect and, if needed, replace:

• Gear lever rubber (145158/B) for proper grip

• Pinch bolt and nut if worn

• Gear shaft splines (if badly rounded, the lever alone may not solve the play)

Q5. How do I confirm fitment for my exact year?
Check your Royal Enfield parts catalogue for your model and year. If it lists 143745 or 143745/2 as the gear lever / foot change lever, you’re safe.
