BODYWORK DAMAGE DISCLAIMER

Even though most of the OS-Base mounts on the seat, the sides can rub against the plastic side panels of the bike, resulting in minor abrasion. This can be further exaggerated if mud and dust get in between the OS-Base and the plastics. We strongly recommend applying a clear adhesive protective sheet to where abrasion may occur on your motorcycle.
