Build finish is not so much better than the 650 I don't think, although mine had a little mis-treatment from the last owner leaving it stood in salty crud for a while so maybe I'm a one off!
Obviously the bike itself is made better to begin with as it needed to cope with the extra horses, so basically things feel beefier than the 650.
