There’s nothing more unsettling than hearing an unexpected noise from your motorcycle chain while riding—especially when a quick stop-and-check reveals no obvious issues. To help you address this problem and handle sudden chain failures, we’ve put together a practical guide based on industry insights.
Why Your Motorcycle Chain Makes Noise (and How to Fix It)
Motorcycle chain noise typically stems from three key issues, each with a clear solution:
Mismatched Chain and Sprocket
If the chain’s pitch (the distance between its links) is larger than the sprocket’s tooth pitch, the two components won’t fit properly—this causes persistent noise. Unfortunately, this mismatch can’t be adjusted. The only fix is to replace both the chain and the sprocket to ensure they’re compatible.
Incorrect Chain Tension
A chain that’s too tight or too loose will rattle or grind during riding. The ideal tension is 25mm of vertical movement: when the motorcycle is in neutral, gently push up and down on the middle of the chain—if the movement falls outside this range, adjust it using the rear wheel adjusters (always tighten the rear wheel bolts afterward to avoid slippage).
Lack of Lubrication
Over time, chains lose lubrication, leading to metal-on-metal friction and noise. To fix this:
Apply the right amount of oil: Avoid over-lubrication, as excess oil attracts sand and dirt (a major cause of accelerated wear). A light, even coat is enough.
Stick to a lubrication schedule: For smooth roads, lubricate every 700–1000 kilometers. After off-road riding or rain, clean the chain first (to remove debris) and then reapply lubricant immediately—moisture and dirt speed up corrosion and wear.
Emergency Handling: What to Do If Your Chain Falls Off Mid-Ride
A chain that slips off while riding can be dangerous, but following these steps will help you resolve it safely:
Inspect the Chain and Components
First, find out why the chain fell off (e.g., loose tension, damaged links) and check if the chain or connecting link is broken. If any parts are cracked or bent, do not attempt to reattach the chain—call for roadside assistance.
Secure the Rear Wheel
Use a wrench to tighten the rear wheel bolts. Loose bolts often contribute to chain slippage, so ensuring they’re firmly fastened prevents the wheel from shifting again.
Adjust the Chain Length
After securing the wheel, shorten the chain slightly (if it’s too long) to prevent re-falling. If you’re unsure how to adjust the length (e.g., removing a link), it’s safer to take the motorcycle to a repair shop later—never ride with a chain that’s too long.
Lubricate the Chain
Once the chain is back in place, add a small amount of lubricant. This reduces friction between the chain and sprockets, lowering the risk of the chain slipping off again.
A Quick Pre-Ride Check to Avoid Trouble
Spending 60 seconds checking your chain before riding can save you from mid-ride emergencies. Simply:
Check for loose links or signs of rust.
Verify the chain tension (aim for 25mm vertical movement).
Ensure there’s enough lubrication (no dry, squeaky sections).
By addressing noise early and following these maintenance tips, you’ll keep your motorcycle chain running smoothly and reduce the risk of unexpected failures. Regular care not only quiets unwanted noises but also extends the life of your chain and sprockets—keeping you safer on every ride.
