Tool kit that I have used many times on other guys bikes, paperwork, several fuses of various sizes, side stand puck on a retrieval string, rain suit, co2 tire filler and plug kit.
The most important thing is several plastic zip lock bags to put cell phones and music players in during heavy rain. Funny how people never think of that and I'm the hero on a ride when the rains come.
*Toilet paper. Something we should have but no room under my seat thanks to the rain suit.
