no doubt the RS and GT are much better looking bikes than the "S" or new GT but then again it's hard to improve on perfection. in my opinion bmw should have kept the styling of the RS and built the new frame and engine around it. while i like the looks of the "S" it does not look better than my RS. looks aside what the "S" and new GT offer over the old bikes is performance ie, more HP, more acceleration, better handling, ESA, all the things serious bikers demand in their bikes. one of the reasons i purchased the RS was BMW's history of longevity. i wanted a bike that would last 100,000 miles plus not something i had to replace ever few years. it remains to be seen how well the new engine will hold up compared to the flying brick and boxer engines. if the new engine holds up then it'll be a real winner if not then BMW will have to go back to the drawing board.
last but not least BMW ought to hire the designer of the MV Augusta F4 tamburini and Senna those are to hot looking bikes that I would buy in a heart beat if i could afford the 48 grand price tag.
