Piece of scrap nylatron, some cap screws and the stock Garmin bracket... -Cut nylatron block with 1 1/8" end mill to wrap the center section of the bar. -Split the block in the center with a saw. -Notch the top block for the top clamp crossbeam. -Drill/tap/counterbore some #10 holes to clamp the two blocks together, pinching between the bar and crossbeam. -Drill/tap hole in the top block for a #10 bolt countersunk into the factory bracket At first I was worried about it being a bit flimsy, but it doesn't shimmy, shake or work loose, even at 80mph or on rough roads. The clip stays and the GPS pops off when I leave the bike. I also wired in a waterproof 12v plug (from the battery) to the right side of the headlight housing, behind the fairing as you might be able to make out in the second picture for charging whatever I happen to have mounted.
I run one of those on my street bike. Not built for outside but has held up for over a year. I simply ziptyed the stock mount tot he triple.
