I carry small 12V compressor, tire plug kit, presure gauge, spare head light bulb, saftey vest, modified tool kit, spark plugs, first aid kit, zip ties, spare fuses, an extenstion cord for my battery tender lead and the clips for it, cell phone and charger, extra gloves, extra layer of clothing, space blanket, a few nuts & screws (bike specific), saftey pins, pad and pencil, multi-tool, small LED flash light, and last but not least tie downs. I had to call triple A once for a tow. Guy showed up in a pickup and small trailer. He was going to tie my bike down like a dirt bike. Make sure you know the proper way to tie down your bike! Handle bars will break off or bend and you can damage the ABS systems on some bikes if you don't know what you are doing. I also carry 2 pairs of black rubber gloves. They keep your hands clean during repairs and you safe if you have to help someone else. A first aid and CPR training is always good to have as well.
