I had this bike as a loaner back in '09 (it was the F650 then) and loved it. I found it very stable and even managed to keep on two wheels during a sphincter-puckering black-ice indcident
I was pretty bummed to give it back but I had it for 6 weeks...they forgot about me
Anyway, not to be judgmental, but have you had any formal training? MSF basic rider class? I took mine after I got my licence and I'm sure it saved my life at least a few times.
Also a class in off-road riding will allow you to feel the wheels slide in a safe(er) more controlled environment and learn how to stay upright.
Just my 2cents, ride safe
