I have one - bought it new in February
I Love it
Compared to the 650 it has tons more grunt - well it will do wont it!
In the wet it's great, holds the road no bother and i've had every confidence in it when riding through some shite weather.
Hauls 2 up fully loaded with tent, panniers etc with ease.
The seating position is much comfier as the pullback is more on the bars.
You can chuck it around better than the 650 - i've scraped the footboards several times (once with a pillion ) cos you forget - it's that light. It has a belt drive too so doing away with the shaft makes it noticably light.
Haven't done any mods yet as it looks the dogs danglies as i is at the mo - but never say never! Plus i'm waitig for the prices of bits to come down cos being a spanking new model, mods cost the earth right now.
Very highly recommended from me - if you want to make the trip - come one over and test ride mine if you like
