i just replaced my bars with tag X5s. when i got the stock ones off, i held the two together and they looked the same (bend and height that is). when you change your bars, you will not have a place to screw the ignition switch console/dash back onto. if you get rid of your ignition switch, you must put the red and solid black wires together (cooling fan/warning light/headlights/brake lights etc). keep the green and black/white wires apart (kill switch) or add kill switch. I used a zip tie for my red warning light. i will post a few pictures if you want to see the finished product. no real opinion on bars here... just my experience. oh yeah... when you remount the light switches/hot start, you must file down a small plastic piece that sticks out unless you want to drill a hole in your new bars. you'll see what i mean.
hope this helps. ^_^
