Chain and sprockets for the Royal Enfield 350 Classic

Match the pitch (520) and tooth counts in the table - chain and sprockets are a matched set, and a mismatched pitch will not fit the sprockets at all.

Frequently asked

What chain size does a Royal Enfield 350 Classic use?

GarageDex's manufacturer-catalogue data shows the 2021-2024 Royal Enfield 350 Classic uses a 520 chain with 15-tooth front and 42-tooth rear sprockets from the factory. (104 links)

What is the stock gearing on a Royal Enfield 350 Classic?

15-tooth front and 42-tooth rear from the factory, part numbers front JTF1022, rear JTR2023.

What changes if I go +2 teeth on the rear sprocket?

Going up 2 teeth on the rear sprocket (or down 1-2 on the front) lowers the gearing: quicker acceleration off the line, but a lower top speed, and the chain usually needs to be 1-2 links longer to keep enough wrap on the front sprocket - a shop or the sprocket's fitment chart will confirm the exact link count for that combination. This is a generic mechanical rule, not a claim about this specific model's aftermarket options.

How many links does a Royal Enfield 350 Classic chain have?

104 links at stock length and gearing, per the manufacturer catalogue.
