Why does my bike chain keep getting loose?

Asked by: Cory Lawrence

A motorcycle chain that keeps getting loose is usually caused by the rear axle or chain tensioning bolts not being tight enough. It can also be cause by a new chain not being worn in enough, worn down sprocket teeth, having too tight of a tension, or having the wrong size of chain installed.
