Had these same pegs on my '08 GS on the highway pegs. Decided that I would use them on the F3 and very happy with them. Used the original peg mounts and did some "garage machine work" to mount them. Extended the shifter peg and will probably extend the brake pedal pad also. Got a few hundred miles on them. Have never been a big fan of narrow foot pegs.
For the positive feed back!
A little hard to see in the picture, but, I also used an old brake linkage and added an adjuster in the middle. Now, I can raise and lower the pedal to my liking. BRP did that on the shifter. Not sure why not on the brake. Would have to lift my foot off of the stock peg to hit the brake pedal. Had one experience of an "Oh S""t" because of the added time to apply brakes. Now I can just move my foot to the left to hit the peddle.
