“Base Plate II” is made to clamp on 1/2” diameter Crossbar of GadgetGuy bracket kits. It can also be installed on the crossbar of enduro and off road motorcycle handlebars via two clamps. Different motorcycles have different diameter crossbars. There fore the difference in diameters should be compensated with shims (GadgetGuy P# AMI0015SSS).
