The bike feels a little heavier with it onbut doesnt really seem to affect the steering. Not sure if heavier is the best word- maybe more planted. Defintely a lot smoother ride with it, but now I'm kind of slouched forward because I dont have the wind holding me up. Heat has been a non issue. Even with the fan running at a stop light in 95 deg temps it hasnt really bothered me. It is noticeable when stopped, but not uncomfortable and definitely not unberable. At speed he is non existant, although if your hands get cold you can warm them up on the valve covers.
