NikosR,
Yes I have them on my 1050 ST.
I had the front and back springs replaced. It was probably not really necessary to change the back but since I was at it I had that done to.
There is not much to say about them, they do there work very good.
I find them a bit hard on a bumpy road, but on the other hand they are great in corners and on the highway.
I know it doesn't help you very much but I don't think about them when riding, I think that is a good sign.
