I bought my malossi delta clutch 2+ years ago. I cannot tell you how long a clutch shoe will last, but I will say Once a year I buy a new belt, and all the springs/rollers for my scoot. Maybe I am lucky? Maybe I hit the right combo for my set-up? I just change the parts as I know they will fail, and for the $50.00 or so I sleep alot better. For the shoes? they look the same as the day I put them in. Maybe 3 years to replace?
