I had a pair on my 900SS. They were the reverse GP shift config. I kept them about six months then sold them. It wasn't because of the sets, it was because I brought a 916 into the stable and I didn't want to convert it to reverse shift. I never could get used to reverse shift, caused a couple of near crashes.
Like someone said, you adjust them once. I know I could have gotten by with sets for less money and frankly, I didn't like the looks of the Acculigns over time. They didn't look "Ducati" to me. They looked like Star Ship Enterprise. I think next time I'm be going with a pair of black sets and be done with it. Having a zillion adjustments is overkill. Furthermore, the Acculign anti-slip cuts in the pegs were too "sticky" for me. What I mean by that is it felt like my boot was stuck to the peg like glue. To some thats good, but not for my riding style. I like to feel the peg underneath my boot and I like a little wiggle room to go along with it. Its a fine line between having too much slip and not enough.
One more thing I had not thought of until someone brought it up here, that is-crashworthiness. My crash history isn't good, I must admit. Its not because I can't ride a motorcycle, shit happens. I think rear set pegs should bend, break or whatever and not play the role of a frame slider. I think being too strong is bad, bad for the frame.
Sorry Brian, just me and my 2 bit opinion. Anything will look good on your bike, see you at Laguna!
