I got beat up by the XX when I first got it but after getting the rear shock setup for my weight and softening the damping on it it was much improved. Also suspension wise it is a known issue that the forks are undersprung and overdamped, you can get new springs and valves that will solve the problem and there are some current threads on this topic.
You can slide the clipons up on the fork tubes about 3/4" without any problem if you remove the retaining clip that is there. Many board members have done either Heli bars or you can use the clipons from an '02VFR, the VFR bars more closely match the fit and finish of the bird than the Heli bars and are cheaper. You can get them at Ronayers.com.
There is a writeup on the main website for upgrading your your grips with some Pro Gel grips these help. There is also a writeup on adding an NEP 3 throttle lock. I have done both of these mods, they are easy to do and help.
Don't let your bird beat you up, a few mods and you will find it much improved. A 300 mile day will be a piece of cake after you get setup.
