I've got Frogg toggs for on my Wing. I've got the one's the golfers wear, not the motorcycle ones....they are very light weight, do keep the majority if not all of the water out, and store in a tiny ball when not in use.
The only thing I'd worry about is if you had exposed pipes, that they would melt as soon as you touched a hot pipe. With my Wing they are great, but I don't know how they'd do on Max....they don't fit real snug, so they might flap around a bit. The thing I like the best is on a hot day's ride and it's raining, they breathe very well...none of the clammy feel you get with the plastic suits.
