NO LIABILITY FOR BODYWORK DAMAGE
Even though most OS-BASE mounts are on the seat, the sides can rub against the plastic side panels of the bike, causing minor abrasion. If mud and dirt get between the OS-BASE and the plastic, it increases the chances of scratching the bike. We strongly recommend applying a clear adhesive protective sheet to areas where abrasion may occur on the bike.
