Bike Chain Care: Clean, Lube & Adjust
A dry or slack chain wastes power, hurts mileage and wears out sprockets. Here is a 15-minute routine that keeps it smooth.
The drive chain carries every bit of power from your engine to the rear wheel. When it is dirty, dry or loose, you lose power and mileage, and the chain and sprockets wear out quickly. A worn chain set is an expensive replacement, while regular care costs almost nothing.
How often
- Clean and lubricate every 500–700 km.
- After every ride in rain or on muddy roads.
- Check slack every 1,000 km or once a month.
Cleaning and lubricating
- Put the bike on its centre stand so the rear wheel turns freely.
- Use a chain cleaner or kerosene with a soft brush to remove old grease and grit. Avoid petrol and harsh solvents on O-ring chains.
- Wipe the chain dry with a clean cloth.
- Spray chain lube on the inner side of the chain while turning the wheel slowly, so it reaches the rollers.
- Let it set for 10–15 minutes, then wipe off the extra lube so it does not collect dust.
Checking chain slack
Push the lower run of the chain up and down at the midpoint. Most bikes need 20–30 mm of free play; check the exact figure on the swingarm sticker or in the manual. Too tight strains the gearbox bearings, too loose can make the chain jump off the sprocket.
When to replace the chain set
If the chain still sags after adjustment, has stiff or rusted links, or the sprocket teeth look hooked like a shark fin, replace the chain and both sprockets together. Fitting a new chain on old sprockets wears it out within weeks.
