Like tires and motor oil, a motorcycle drive chain and its sprockets are consumable components – sooner or later they will wear out and need to be replaced. The rate at which the chain and sprockets wear can be quite variable, depending on where and how you ride, the type of motorcycle you ride, and how well you maintain the driveline. As a motorcycle owner, it is good practice to inspect your motorcycle chain and sprockets for wear and tear on a regular basis. Here’s what to look out for when it comes to motorcycle sprockets and chains.
A well-maintained motorcycle chain can usually last 15,000 to 20,000 miles, or even longer. The sprockets should likely outlast the chain. Bikes that are ridden off-road expose the chain and sprockets to abrasive sand and dirt that will accelerate chain wear. A chain that is cleaned, lubricated and adjusted regularly will most likely last longer than a chain that is allowed to accumulate crud. Because the chain and sprockets function as a system, a well-maintained chain may also extend sprocket life. It’s recommended to maintain the driveline and inspect your chain regularly, and then replace it and the sprockets when they show signs of excessive wear.
On most motorcycles, the chain is exposed and easy to inspect. On bikes with side cases or saddlebags, you may need to remove the luggage to see the chain. Follow these steps to inspect your motorcycle’s chain:
