go to this site...check out #21....all are great tips for riding.....long distance or even a short run....never know when you or another rider may need them....
I put allen wrenches, Flashlight, Screwdrivers, Metric wrenches, Ratchet with extension and plug socket, 10 & 12 mm sockets, tire gauge, small pair of channel lock pliers, adjustable wrench and a pair of gloves. I have never needed them for my bike but my friend used some of them on his HD one time.
