I had one for a few years. Something's up with the steering, it should be pretty light & flickable (even for a 19 inch front wheel). I'd say headset bearings, badly worn front tyre or wrong size front tyre (bigger is not better).
When set up properly they handle really well (except at 180 kmh + in a straight line, then you get the "death wobble").
The motor's are a little fragile. The CB1100F is a better bet (gee I love them in metallic red/white!).
