The RAM-B-174-GA63U consists of a hardware for mounting to both brake/clutch reservoirs and rails that are 0.5" to 1.25" in diameter, double socket arm and Garmin VIRB™ camera adapter. The mounting hardware for brake/clutch reservoirs include both standard and metric mounting bolts. To see if the base will mount to your motorcycle, check the hole spacing of the base against your clutch/brake reservoir. The holes centers have a minimum width of 0.94" and a maximum of 1.58". The mount is designed with a RAM 1" diameter patented rubber ball and socket system that has adjustment points at both ends of the double socket arm; this allowing for almost infinite adjustment and perfect viewing angles. The adapter attaches directly to the under-side of the camera, replacing the factory mounting bracket.
