Our client brought in his Honda CRF 250 to get a fully removable board rack fitted. Normal board racks have easily removable board carriers but the main support remains on the bike. Steve wanted the whole structure to be removable so that it didn't get in the way when riding offroad.
We fabricated a custom, detachable mount for the racks, fitted over the rear fender. The mount and racks can be quickly removed by undoing 4 bolts.
