Value Accessories has the best price, they are listed like everyone else's price but when you pay them you find you have a very nice discount. I paid $364 for the chrome and they are gorgeous on the F6
Personally, I would NOT stand on mine whether anyone else has done it or not. I'm sure they weren't designed for that. If I want to stand while riding, I use the regular foot pegs. That said, I'm quite satisfied with my Aero pegs, especially the hidden-look feature .
I have the silver pegs, and love them.
Great mod, and super easy installation.
They also seem extremely sturdy.
But their positioning on the bike is such that I do not think I would ever want or need to try to stand on them for any reason anyway, so I'm not concerned about verifying whether or not they can actually handle my full weight on their own.
