Do you lane-split or filter much? Every review of the Duke HyperMotard I've read has noted that its bar-end mirrors make the bike wider and therefore lane-splitting harder, unless each time you need to nip to the front of the queue you have the foresight to bend both mirrors back.

If you're not lane splitting much its not going to be a problem, but something to consider if you commute very day through the parking lots we call "main roads".
