The RAM-B-174-GA63U consists of hardware for mounting to both brake and clutch reservoirs and rails that are 0.5" to 1.25" in diameter, a double socket arm, and a Garmin VIRB camera adapter. The mounting hardware for brake and clutch reservoirs includes 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 or brake reservoir. The hole 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, allowing for almost infinite adjustment and perfect viewing angles. The adapter attaches directly to the underside of the camera, replacing the factory mounting bracket.
