I would add that the 500 EXC with DS attachments also works very well indeed. I do not mean to cut these uses out entirely but my emphasis is using the 500 to its extreme potential. I rode very long trails in Utah on my 500 with DS attachments but I rode extreme trails that most DS riders don't attempt. I want to know what is possible on this bike with competition accessories. These always work better even for DS riders, in my experience.
