This is a tool to open the strange cap on a 2011 BMW R1200 GS and similar models. It also has a 10mm hex cut out to be able to adjust the wind screen bolts. Voids have been made to be able to install 8mm magnets if desired. This tool is much smaller than the one that comes with the bike's tool kit, and works with the bike's key. I keep mine on the windscreen bolt as pictured. I made this with a Rostock Max using ABS.
