Royal Enfield RAT00218/D Chain 520, 103 Link is a genuine rear drive chain used on compatible Royal Enfield J-Series 350 motorcycles where this exact chain specification is specified. It is commonly searched as a Royal Enfield 520 chain, 103 link chain, rear drive chain, sprocket chain, Meteor 350 chain, Classic 350 Reborn chain, Hunter 350 chain or Bullet 350 J-Series chain.
This chain transfers power from the front sprocket to the rear sprocket and directly affects acceleration smoothness, drivetrain noise, chain slack stability and riding feel. A worn or stretched chain can cause jerks, chain slap, khat-khat noise, uneven sprocket wear, poor pickup, vibration during throttle changes and frequent chain adjustment. Replacing it with the correct genuine Royal Enfield 520 x 103-link chain helps maintain the factory drivetrain specification on compatible J-platform 350 models.
Public Royal Enfield parts references identify RAT00218/A as Chain, 520, 103 Link. Current Indian seller references list RAT00218/D for the same 520 pitch, 103-link rear drive chain used on modern Royal Enfield J-platform 350 motorcycles including Meteor 350, Classic 350 Reborn, Hunter 350 and latest Bullet 350 applications. This listing targets the current buyer-search suffix RAT00218/D while also covering the RAT00218 / RAT00218/A search family for discoverability.
Use this genuine Royal Enfield chain only where RAT00218/D, RAT00218/A or the RAT00218 Chain 520, 103 Link reference is specified in the chain and sprocket / final drive parts diagram. This is not a chain sprocket kit, not a 104-link chain, not a 525 chain, not a master link-only listing, and not a universal aftermarket chain.

When Should This Chain Be Replaced?
- Chain has stretched beyond adjustment range
- Frequent chain slack adjustment is required
- Chain makes khat-khat, slap or rough rolling noise
- Links are stiff, rusted, kinked or unevenly moving
- Sprockets show hooked teeth or uneven wear
- Rear wheel adjustment marks are near the end of usable range
- Chain has tight spots after cleaning and lubrication
- Final drive is being restored with genuine Royal Enfield parts
Why This Part Matters
The rear drive chain is one of the most important wear parts in the drivetrain. A worn chain can damage sprockets, increase noise, create jerky throttle response and reduce riding confidence. Replacing only the chain without checking sprockets can also shorten the life of the new chain if the sprocket teeth are already worn.
Using the genuine Royal Enfield RAT00218/D helps maintain the correct chain pitch and link count for compatible J-Series 350 motorcycles and reduces the risk of wrong-length chain fitment.
