Man, remove kickstand from bike, place the foot of it on the ground where bike was standing, and smack the ****er with a hammer. Tell them act of God, pavement cracked from sitting in same possition for 4 months. Bike fell as a result. They cannot prove you wrong. My kickstand /centre stand in fact does crack and dig into asphalt after sitting in the same place for a week, there's potential for it to happen on concrete aswell with such a long duration of time
sometimes you need to tell a little white lie to get your proper coverage
This will be comprehensive, and they can "f" themselves!!!
(The centre stand being on a 84 vt500c Honda shadow not the 08 ninja )
