I just put the Hyperpro progressives on my 2010 F800GS. I went with the "touratek big tank" stiffer spring.
Also swapped for skf seals and replaced the inner and outer bushings.
BMW bushes were more than I wanted to pay. I ordered from Innteck, and I wasn't sure the bushings were correct when ordering since I couldn't find that they were for my bike specifically, but they were perfect. Part numbers below.
Big improvement.
