My personal experience (when I went from an 05 with suspension upgrades to a 08) was that I was very happy with the OEM suspension on the 08 until I tried (unsuccessfully) to keep up with some good riders on twisty roads.. The first time I blamed myself for poor riding, the second time I was riding behind riders that I knew were not any faster than I was so I concluded that it had to be the bike's soft suspension that was holding me back. This was confirmed as soon as I transferred my 05 suspension upgrades to the 08.
