Then if you are in some god forsaken place and it snaps on you all you have to do is hook up the spare and you are rolling again.
Get a good tune up before you leave, sync the carbs, bring some extra tubes, get some good modern tires, put together a good tool kit, what ever other replacement parts you think might be necessary and split!
Have fun! Whatever bike you own is the best one to take! I've been on long rides on a cb-750 and they are rock solid reliable.
If people keep waiting for the right bike to do the trip, they sometimes don't do the trip. The fun in motorcycling, as I see it, is going with what you have and having fun on the way!
