I've ridden both but have more time on a RG. In the looks department I prefer the RG and it does handle better without all the junk mounted to the forks. At very high speeds you really need a frame mounted fairing, but for the average rider it wouldn't make that much difference. I don't think either one has the edge on wind protection. The frame mounted fairing with lowers wins hands down in in the rain and I'm sure all of us can agree on that.
In my opinion we need a better designed frame mounted fairing with integrated lowers for rider comfort and to hide the plumbing on the 150/150 wet motor that will come with it. For now I'll take second best, my SERG. Doc
