I bring a backpack with me on my trips, but I only use it for very light items, my empty water bottle( to be re-filled at the campsite) my sandwich I bought for lunch, extra shirt, or extra gloves....stuff like that.
Maybe a map or two.....I will try to post a pic of my bike all decked out for traviln' n' campin'. I tell you though, I have come close to dropping it, oh, about a million times. It gets heavy with the gear on it and I have to maneuver it around gravel roads, uneven camp grounds ect.
Man, for me its a workout. But I am 5'4 and 120 lbs so YOU try to muscle around a fully loaded busa by yourself!!!
