The RAM-B-309-7U combination accessory base, with 1" ball, connects to your handlebar clutch/brake clamp, left or right side or mounts on any handlebar or rail. The base fits the control clamps on your motorcycle with 40mm x 6mm stainless steel hardware, or bars from 0.50" to 1.25" with U bolts provided in the kit.
This RAM mounting base will fit Goldwing, Harley Davidson and pretty much all other motorcycles. The perch mount holes centers have a minimum width of 0.94" (24mm) and a maximum of 1.58" (40mm). If you are not sure if the RAM-B-309-1U base will mount to your motorcycle, check the hole spacing of the base against your clutch/brake reservoir.
