Keep the safety cut-off working exactly as the factory intended with the genuine Royal Enfield 581738/A – Side Stand Switch. This is the OE side-stand sensor that tells the ECU/ignition your side stand is down so the bike won’t ride off with the stand still dropped. We cross-checked multiple dealer sources: Bike-Parts-RoyalEnfield lists “SIDE STAND SWITCH – 581738/A”, Indian exporters list it as “Side Stand Switch – Bullet X / Thunderbird 350 | Thunderbird 500”, and several international sellers show the same part number for Royal Enfield Himalayan 411 and Bullet 500 Euro 4. That gives us a clean, confirmed fitment set below. No guesswork. 

Because it’s OEM, you get the correct 2-wire connector, cable length, grommet and mounting holes, so it bolts to the stock side-stand bracket and plugs straight into the original harness—no cutting or splicing. Replace your switch if the bike cuts out when you select gear with the stand up, or if the stand-down warning is always on.

FAQs

Q1. My bike starts in neutral but stalls when I put it in gear – is this the part?
Yes, that’s a classic bad/misreading side-stand switch symptom on the models above. Replace with 581738/A.

Q2. Can I bypass the switch?
We don’t recommend bypassing a safety device. Fit the correct OEM switch so the stand-down protection remains active.

Q3. Is the connector the same on all bikes listed?
For the models above, yes – sources show the same 581738/A used across TB 350/500, Bullet X and Himalayan. If your connector looks different, send VIN/pic before ordering. 

Q4. Does it come with bolts?
Generally just the switch with lead. Reuse your OE mounting hardware.

Q5. Do I need to reset ECU?
No. Fit the new switch, clear any moisture, and test by moving stand up/down with engine running.
