I have the Renthal Ultra lows on mine (man, so much better than the stock bars)
I've had 'em on there for a month or so now (about 1.5k miles, give or take).
I had originally planned on leaving them alone, but I decided a while back that I think I'd like to cut them down a little.
Over the last few days, my mind has been made up..
I'm lopping 20mm off the ends this weekend. (If I get the time).
I do a lot of commuting in peak hour traffic. Two lanes going nowhere fast and I'm a dedicated lane splitter. That extra 20 mil may not sound like much, but that will bring the overall width back to about the same as my old VF400. I got very used to my width on that bike and the sort of gaps I could pop through.
A kind of sixth sense if you will.
I've knocked the bloody mirrors a couple of times now. It's only light, but enough to shift the thing. Plus I don't immagine the tin tops appreciate it either.
And there's no way I'm gonna sit there in line like a ... well.. like a line sitting person...
The stock bars were pretty close, but the ULs in stock form are just bothering me too much. That 20 mil has gotta go.
Oh, there's also the issue of oversensitivity to input. At least for my preferences.
The extra width does, as Mike says, make the steering "lighter", but I found the steering pretty light and quick as it was. The added length just makes it a tad too sensitive to involuntary input for my liking.
This is my primary reason for cutting 'em down! The lane splitting thing was just the clincher.
