Quite a few members have tried similar systems.
I think they do their job well, but they can push your feet out a little (depending on position they're in), the distance to the gear/brake toe peg may change and the height can also change. Just things to consider.
All true but the changes are reasonable. I could definitly feel the width but it only took a ride down the block to get used to it. I have mine (similar madel) aimed back & down a click and no problem with distance to the shift/ brake levers.
Money well spent, I think. I'll probably put them on my SS, too.
