What kind of bikes are the guys taking, and where are they going?
From quickly glancing over the list, they have way to many tools. Usually the stock tool kit will do most anything that you can do on the side of the road, especially if combined with a good multi-tool. If you plan on rebuilding the engine, by all means take the tools, but if you do your maintenance before hand, you should be good to go unless you have a flat, blown fuse or bulb.
Another thing that caught my attention is the hatchet, entrenching tool, and fixed blade knives. I am a knife guy and have way to many but seriously, I have never needed a hatchet or fixed blade knife in 100k + miles of two wheel travel. Leave the flashlights at the house and get a headlamp, a lot smaller and easier to handle if working on the bike or setting up camp. Ditch the canteens. The camelbak should hold enough water to get you from one watering source to another, unless you are in the desert.
I'm thinking that half of the stuff gets shipped home or thrown away. Either way, good luck to them.
