I try to have just about anything in there. Not just for me, but those I meet along the rd. side.
Here is what may be obvious, but I have found the best things that everyone needed.
1. black electrical tape
2. various sizes of zip ties
the small type bungi cord (great when your buddys kickstand spring breaks and wants to keep droping)
3. flat tip and phillips (smaller size)
4. pc of vacume or fuel line for spark plug removal
5. swiss army knife / leatherman
6. coupple of wratchets. (the cheep ones. cause if you loose them its not a big loss)
7. main size sockets for our bike (8, 9, 10 mm)ect.
8. a good adjustable wrench (IE Chineese socket set)
9.a mini mag light. (dont have one yet, but they are indespenceable, you can hold it in your mouth and haveboth hands to work)
metric allen wrench set and a star drive set (as you know a must for getting to your battery!)
I also use a larger standard size allen set foradjusting my shocks.
air stick
D tool from brent.
I think that fills out my bag. its what ever you feel comfy with.
I keep my cell phone and wallet in my tank or saddle bag.
