8mm threaded holes for mounting a GPS, tach or other gauge.
Eliminate the ugly U-bolt clamps used for many accessories. These have 8mm threaded holes for mounting a GPS, tach or other gauge. You can also fasten a bar between them to have multiple mounting points or a solid center mount.
These work especially well with G/S and GS models to bring the gauges forward a little without a long bracket that vibrates. Shown below with a RAM ball mount for the GPS on my 91 R100GS-PD.
