Quick answer: Most 150cc+ sport and cruiser bikes use a sealed O-ring chain. Clean it with a dedicated chain cleaner — never petrol or kerosene, which swell and crack the rubber seals — dry it, then apply an O-ring-safe chain lube every 500 km.
Why O-ring chains are different
Tiny rubber O-rings seal factory grease inside every link. That grease is what gives the chain its long life — but harsh solvents destroy the seals, the grease escapes, and the chain wears out fast and turns noisy. So on a sealed chain, product choice matters more than on a basic commuter.
Step-by-step
- Put the bike on its stand so the rear wheel spins freely.
- Spray chain cleaner, scrub with a soft brush, wipe off the grime.
- Dry the chain fully.
- Apply chain lube to the inner run, spin 2–3 turns, wait 10 minutes, wipe the excess.

FAQ
How do I know if my chain is O-ring? Look for small rubber rings between the side plates. Most modern 150cc+ bikes have them.
Can I use petrol to clean it? No — it destroys the seals. Use a proper chain cleaner.
