I am actually torn between the two... I guess if most of your riding is dicing through the trees on single track here in the south, then the 350 is the heat. But if you plan on doing some street time with it and dicing the trees with some occasional mountains and desert thrown in, then the 500 is the ticket.. IMO. Make no mistake, that 500 can do it all.. For wee seen it first hand with a few folks. Need to get Vic and the other gentleman with the new 350 and test ride them both and make a decision.. come on hook the man up fellas.. bring those bikes out and let man test them both.. HS two days away, looking forward to it..
