My driveway is gravel and this $7 ABS support saves me a lot of trouble.
Twice I've walked away from a bike only to hear it crash down in my drive a few minutes later. You'd think I'd have bought this support after the first incident. This small, fitted ABS sheath increases the footprint on my motorcycle kickstand, helping to keep the bike from sinking into wet or soft ground. It also helps keep the bike from sliding on the loose gravel in my driveway.
Simple to use. Cheap enough I won't mind occasionally losing them.
