I've always used an old Army Rain Parka ( the new Nylon won't keep squat off ya). Make sure it is the rubberized one. Just tie one side corner too Handlebars, and other side corner to the sissy bar with 550 cord. Pull over bike, tie off to dufflebag. ( all items in Duffle should be in Army waterproof bag ) That way duffle can be in under the Parka , or , outside wont hurt anything. Depending on room put duffle on inside or outside. To hold tarp use 550. ( warning not bear proof )be using this sence 1979. Never failed me yet.Very lite weight. Get a Army Survival sleeping bag. very light but warm.This is an old thread. I haven't been on here for a while. I found a couple of cheap, new, 1- 2 person tents and cut all the individual tent poles in half and put the end pieces together so they fold up well. Then I threw out what was left of the other tent. It fits in a saddlebag and a regular backpack easily, with the tent poles. It also cost me less for two walmart tents than buying replacement pole kits and a tent along with it.
