I have the SM and love it, range is okay but we've talked about that already, I'd be lying if I said I had not thought about buying the MX-R and putting my SM wheels and forks on it, how bada$$ would that be, illegal as heck on the street but they'd have to catch me:) I was getting caught up in all the new specs on the MX-R, which are great but I took the bike out yesterday and am still thrilled with the performance from the old girl...
