Genuine Rolon BSOR 207 chain & sprocket kit for Royal Enfield Continental GT 535.
Correct 18T front sprocket, 36T rear sprocket and 100-link chain setup for the original Continental GT 535 single-cylinder café racer.
Fitment warning: This is for Continental GT 535 only. It is not for Continental GT 650, Interceptor 650, Classic 500, Bullet 500 or other Royal Enfield models.
Rolon BSOR 207 is a genuine chain and sprocket kit for the Royal Enfield Continental GT 535. The verified kit setup is 18 teeth front sprocket, 36 teeth rear sprocket and 100-link chain. This is the key fitment detail to check before ordering because Continental GT 535 is often confused with the newer Continental GT 650, which uses a different platform and chain-sprocket setup.
This kit is useful when the motorcycle starts showing drivetrain wear symptoms such as jerky pickup, khat-khat chain noise, chain slap, tight spots, rough throttle response, rusted chain links, hooked sprocket teeth or frequent chain adjustment. Replacing the front sprocket, rear sprocket and chain together helps restore smoother power transfer and prevents a new chain from wearing quickly on old sprockets.
The Continental GT 535 is a 535cc UCE single-cylinder café racer, not a 650 Twin. BSOR 207 should therefore be listed and sold only for GT 535 applications where the existing setup matches 18T/36T/100L. Do not merge this listing with Royal Enfield 500cc kits such as CL271/CL273 or with 650 Twin kits.
Under The Hood supplies genuine fitment-focused spares with careful packing and buyer support so riders receive the correct Rolon kit code instead of a mismatched chain-sprocket combination.

Installation & Maintenance Notes
- Install at a professional Royal Enfield workshop for correct alignment, chain slack and torque.
- Replace chain, front sprocket and rear sprocket together; do not run a new chain on worn sprockets.
- Before installation, confirm your current setup is 18T front / 36T rear / 100-link chain.
- Check model carefully: GT 535 and GT 650 are completely different platforms.
- Check front sprocket spline and rear sprocket hub pattern before dismantling.
- Maintain chain slack as per Royal Enfield service manual for the Continental GT 535.
- Clean and lube regularly, especially after rain, washing, dusty rides or long rides.
- Avoid direct high-pressure water jet on the chain and sprocket area.
- Re-check slack and wheel alignment after the first 200–300 km as the new kit beds in.
- Inspect rear hub dampers during installation; worn cush rubbers can still cause jerks even after fitting a new chain kit.
FAQ
Will Rolon BSOR 207 fit my Royal Enfield Continental GT 535?
Yes, BSOR 207 is listed for Royal Enfield Continental GT 535 with 18T front sprocket, 36T rear sprocket and 100-link chain. Verify the existing setup if the motorcycle has been modified.
Will this fit Continental GT 650?
No. Continental GT 650 is a different twin-cylinder platform. BSOR 207 is for the older Continental GT 535 single-cylinder model only.
Is BSOR 207 for Classic 500 or Bullet 500?
No. Do not assume Classic/Bullet 500 fitment. Those applications use separate Rolon kit codes, such as CL271 where applicable. BSOR 207 should stay focused on Continental GT 535.
What are the sprocket teeth and chain length?
The confirmed setup is 18T front sprocket, 36T rear sprocket and 100-link chain.
Is this a brass chain kit?
No. This listing should not be sold as a brass chain kit unless the actual product packaging states a brass BSORC variant. BSOR 207 is listed as a regular BSOR chain and sprocket kit.
Is this X-ring or O-ring?
This listing does not claim X-ring or O-ring construction unless confirmed from the current Rolon packaging. The confirmed customer-facing details are BSOR 207, Continental GT 535, 18T front, 36T rear and 100-link chain.
Will this reduce chain noise, jerks and chain slap?
Yes, if the issue is caused by worn chain links, hooked sprocket teeth, tight spots, rust or incorrect chain adjustment. Also inspect wheel alignment, cush rubbers and rear wheel bearings.
Should I replace only the chain?
No. For best life and smooth running, replace the chain, front sprocket and rear sprocket together.
Why buy from Under The Hood?
Under The Hood focuses on correct kit-code fitment, genuine sourcing, safe packing and buyer guidance, which matters because the wrong rear sprocket teeth, chain length or GT model confusion can cause installation failure.
