I got mine from AmericanSportBike and that's the price.
I went for the longer/-7 for a more natural grip, also, I didn't like riding with flat wrists...
In the end it's all personal preference I guess... I really like the black plate, and if you got the shorter bars, the controls would pretty much cover the silver color of the actual bars...
I forgot who had the bars, but he re-routed his clutch cable through the fly-screen. I didn't do this and now the cable is rubbing on one of the bolts of the new bars. No big deal, the rubber part of the cable is a little torn, but the metal housing is still intact. That has been the ONLY downside to the bars.
Don't forget the new grips with the order. I got the Buell traction grips and they come with everything you need. Real simple swap! The traction grips have ends on them already, so you don't need caps or anything.
