RAM now has in stock and available for shipping a 1" ball mount with a M8 bolt (actually they include three bolts of various lengths in the kit) so we ST riders can replace one of the bolts mounting the handlebars to the triple tree with a ball mount for a GPS or radar detector, etc. I ordered a RAM-B-367U directly from RAM about three weeks ago, and got an email saying they were not in stock and expected to ship in December, but the kit arrived yesterday. I'll mount up a waterproof box on a 3" arm for my GPS this weekend.
I have no affiliation with RAM, just a customer. I couldn't justify the expense of the Telferizer ball mount, so I waited for the RAM mount to be available (approx. $11 US each, plus shipping, if I remember correctly)
