You drop a bolt and it falls inside the bike. I find the small 6mm bolts holding on the glovebox are especially happy to leap downwards and find a special place to stay warm on top of the motor. Triple clamp bolts like to play hide-and-seek also.
You know you're a truly special 950 owner when you do this and you have full fuel tanks so they swell and are a general pita to put back on.
You get special bonus points if you happen to have the original SW Motech crashbars installed
