I find them to be quite a bit wider. Not necessarily a problem and I'm pretty well used to them now but a little goes a long way as they say.
I've yet to ride mine with them fitted, but that's the thing that worries me - I really didn't want wider bars, because I had wider bars (The MoCo's Touring Pullbacks) on my '03 Ultra, and didn't like them being wider. Having short arms (and body, and legs!) is why I needed the further up/back bars in the first place, I found that wide bars were harder to make very tight, slow turns with. Once Spring is here, and I get to ride it I'll see how they feel, and I hope I don't dislike them (Jeez, I'd hate to go through the pain of changing them back!) but why they have to be wider is a mystery to me.... They don't say on their site they are wider, as far as I recall, which is a bit of a serious omission.
