Looks like this got out of hand in a hurry....it's like asking snowmobilers, which track length is better.

Here is what I bring on every outing, never leaves my ATV, and alway's double checked.
Small rolled up socket set W/ Ratchet- "From my Old Gold Wing tool kit"
Cresent wrench- 8"
CO2- inflater (4) cans, and plugs
Leatherman
Bail wire- small roll
Duct Tape-small roll
Tow Strap
Spare plug.

And the stock tool kit.... all this list fit's in the storage compartment under the seat....and always avaiable !
