Genuine Rolon SOR 438 NF noise-free chain & sprocket kit for Royal Enfield Guerrilla 450.

Correct 15T front sprocket, 45T rear sprocket and 113+1 link chain setup for the Guerrilla 450 roadster platform.

Choose this when you want the regular/noise-free Rolon replacement kit for Guerrilla 450—not the Himalayan 450 kit and not the brass SORC 462 NF option.

Rolon SOR 438 NF is a noise-free chain and sprocket kit for the Royal Enfield Guerrilla 450. The verified fitment setup is 15 teeth front sprocket, 45 teeth rear sprocket and 113+1 link chain. This is the main specification to check before ordering because the Guerrilla 450 does not use the same rear sprocket setup as the Himalayan 450.

This kit is useful when your Guerrilla starts showing drivetrain wear symptoms such as chain slap, khat-khat sound, jerky low-speed pickup, tight spots, uneven pull, 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 avoids fast wear from mixing a new chain with old sprockets.

The Royal Enfield 450 family has multiple chain-kit combinations. SOR 438 NF is the regular/noise-free Guerrilla 450 kit with 15T/45T/113+1L. The brass Guerrilla option is commonly listed separately as SORC 462 NF, while Himalayan 450 / 452 kits use a 47T rear sprocket and 116-link chain. Do not interchange these kits just because the motorcycles share the 450 platform.

Use SOR 438 NF only when your motorcycle matches the 15T/45T/113+1L setup. Under The Hood supplies genuine fitment-focused spares with careful packing and buyer support so riders receive the correct kit code instead of a mismatched chain-sprocket combination.

Likely / Popular Retrofits — Check Before Ordering

  • Modified Guerrilla 450 bikes only if sprocket teeth, chain length, rear hub pattern and front sprocket spline match.

Not Compatible / Common Confusion

  • Not for Royal Enfield Himalayan 450 / Himalayan 452; those use 15T/47T/116L kit setups.
  • Not for Himalayan 411 or Scram 411.
  • Not for Classic 350, Hunter 350, Meteor 350 or other J-Series 350 models.

  • Not a generic “all Royal Enfield 450” chain kit.
  • Do not sell this as brass; the brass Guerrilla 450 kit is SORC 462 NF.
  • Do not claim X-ring or O-ring unless confirmed from the current Rolon box.

FAQ

Will Rolon SOR 438 NF fit my Royal Enfield Guerrilla 450?

Yes, if your Guerrilla 450 uses the 15T front, 45T rear and 113+1 link chain setup. Always verify your current sprocket teeth and chain length before ordering, especially if the bike has been modified.

What is the difference between SOR 438 NF and SORC 462 NF?

SOR 438 NF is the regular/noise-free Rolon kit for Guerrilla 450. SORC 462 NF is the brass kit option for Guerrilla 450. Both are separate products and should not be merged into one listing unless you create clear variants.

Will this fit Royal Enfield Himalayan 450?

No. Himalayan 450 / 452 kits use a different setup, commonly listed with 15T front, 47T rear and 116-link chain. SOR 438 NF is for Guerrilla 450 with 15T/45T/113+1L.

Is this a brass chain kit?

No. SOR 438 NF should be treated as the regular/noise-free kit. If the customer wants the brass Guerrilla 450 kit, use the separately listed SORC 462 NF where fitment matches.

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 details are SOR 438 NF, Guerrilla 450, 15T front, 45T rear and 113+1 links.

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 adjustment. Also check wheel alignment, cush rubbers and bearings during installation.

Can I use this on Himalayan 411 or Scram 411?

No. Himalayan 411 and Scram 411 are different platforms and require different chain-sprocket kits.

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 or chain length can cause installation failure.
