I have GPR under bar mount on my KX250, I love it on the roots and rutted out trails around here, it has also completely stopped the twitchy feeling my bike had at max speed. I only have it dialed at 2 1/2. thinking bout having them revalve it for more sensitive adjusting, might just be able to bleed it out and use a lighter fluid, but it works great where i have it set so I'll look into that further once it needs rebuilding.
