How do you know if your motorcycle sprockets are worn?

How do I know if my sprocket needs replacing?

If it is, you need to replace the sprocket, and your chain is probably toast, too. At the far back end on the rear sprocket, pull the chain away from the teeth parallel to the ground. A new chain will barely move. If you can pull it back to expose half a tooth or more, you need to replace the chain.

How long do motorcycle sprockets last?

A common rule is to replace both front and rear sprockets every time you replace your chain. This is a good rule to follow if your chain has lasted for its full life of, say, 15,000 miles. But, sometimes a sprocket replacement can wait in cases where you’re replacing a prematurely worn chain.

How do you know if you have a bad sprocket?

Worn sprocket teeth are clingy. They hold on to the chain longer than needed. Sometimes the chain can even climb the teeth. This interaction will make a lot of noise.

What causes sprocket failure?

Chain wear and stretch will cause grouping and excessive wear to the sprocket, a major cause of whipping. Poor Sprocket Alignment creates heat and may even bend the shafts on the drive system, causing great damage. Poor Pitch Integrity of chain and sprockets also causes premature failure.

What is the life of chain sprocket?

As everyone suggested, it depends on your riding style and frequency of your maintenance. But as per my experience with proper lubing & optimum chain slack, the approximate life of the chain sprocket should be 20k to 25k kms.

How do I know if my chain is worn?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

When should I change chain and sprocket?

Your sprockets and chain are typically changed as a pair with 520 chains lasting up to 25,000 km and 530 chains 40,000 km if you keep clean and lubricated every 500 km.

Should I change the front or rear sprocket?

Doing the rear is better from a chain and sprocket wear perspective. A smaller front sprocket will excert more force on the chain and wear it and the sprocket faster which is why most will tell you to do the rear. If changing front, I would recommend against more than -1.

How long does a chain last on a motorcycle?

On average, you can expect to replace your chain and sprocket between 20,000 to 30,000 kilometers, less if you ride fast and hard. However, if you spot any damage to your chain or sprocket, it’s better to just go and replace the prematurely-worn part right away.

How often do bike chains break?

How often should you clean your motorcycle chain?

2. Cleaning: The chain should be cleaned before each lubrication, as the combination of dirt and grit with chain lube/grease can make a ‘grinding paste’, severely reducing chain life. If that isn’t possible, aim to clean the chain every 750-1000miles.

Why does my motorcycle chain have a tight spot?

The most common cause of chain tight spots is that your sprockets are not as concentric to the wheel or gearbox output shaft as they should be, IE running “out of true”. This can be due to wear, poor quality sprockets or chain, or poor fitting.
