The bike is heavier to push if you dont have what you need.

As mentioned above, "work out of your fanny pack" at home in the garage a couple times. you will figure out what is missing or needed.

Cant stress this part enough...
Carry ANYTHING that is special to your bike. Others may have tools. but YOUR Plug or YOUR Masterlink may be different from what they have.

I think the most important item is the "Tow Rope" if all else fails it is a MUST HAVE item. I carry the long half of 12' tie down, not the buckle end. It also gets you up cliffs, over HUGE slimy rocks, down ravines, out of mud bogs, and yes, you can tow a broke bike too...
