Another, much easier way to check for a worn chain is to try to pull the chain away from the rear of the sprocket on the rear wheel. If the chain is worn, you’ll reveal about half a tooth of the sprocket. A new chain will wrap around the sprocket snugly and won’t pull away.
How do I know what kind of sprocket I have?
Number of sprocket teeth or sprocket diameter. . . The easiest way to determine the number of teeth is simply to count them. Sometimes, however, the teeth are totally worn away. In this event, the caliper diameter may assist in identifying the sprocket.
How long does a sprocket 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.
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.
How do you match sprockets?
To determine the final drive ratio, divide the rear sprocket size, say 49 teeth, by the front or countershaft sprocket size, say 13 teeth (like a new Yamaha YZ250F). In this case, the Final Drive Ratio is 3.77 – the front sprocket revolves 3.77 times to make one complete revolution of the rear sprocket.
How big is a 60 tooth sprocket?
Inside Diameter: 1.1245 in. Thickness: 0.086-0.092 in.
How do you pick a sprocket size?
Determine the number of teeth of the small sprocket. The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is recommended. The number of teeth on the large sprocket should be less than 120.
How long do dirt bike chains last?
A new chain dirt bike chain can last between 700 and 5000 miles. However, it all depends on your riding style and maintenance. Be sure to always ride with a chain that’s in a good condition, because it directly affects the bike’s performance and your safety.

What can a loose motorcycle chain cause?
The major symptoms of a loose chain include chain teeth skipping over the sprockets, uneven transmission of power to the wheel leading to jerky wheel movements, chain lash and the chain slapping the swindle arm, and in the final case, chain coming off the sprocket.

How many teeth does a bicycle sprocket have?
Depending on the type and age of your bike, it will probably have between 9 and 12 sprockets and will be referred to as 8-speed or 12-speed respectively. On a typical road bike, the smallest sprocket will typically have 11(11t) or 12 (12t) teeth and the largest 25 (25t) to 32 (32t) teeth.
How many types of sprockets are there?

Type B sprockets, which have a hub on one side. Type C sprockets, which have hubs of equal thickness on both sides of the plate.
How long do chain sprockets last?
It depends on the way you maintain it. If the chain was cleaned and lubed properly for every 400–500 kms, it will last upto 32k kms(it’s my personal experience) and if the maintenance was too poor, the entire set along with both rear and front sprocket will wear off within 15k kms.
How often should a motorcycle chain be lubed?
A motorcycle chain should be lubricated every 300-600 miles to ensure peak performance and a long life. Lubricate the chain after riding, not before. This allows time for the solvents in the spray to evaporate before the bike is used again, and lets the lubricant penetrate the link properly.
Can you put a new chain on old sprockets?
Normally, chains and sprockets should be changed at the same time. To not do so may cause accelerated wear on both the new chain and the old sprockets. If your old chain had stretched enough to need changing, you can bet the sprockets are worn, as well.
