I use the GPR. Nice Product.
What I didn't like about the HESD:
A. If you enter a corner slow and leave much faster, the front feels different because the HESD has kicked-in. It is doing it's job, but I need the feel to be the same all the time.
B. Damping isn't just for headshake. I REALLY want damping when I brake too late and the front gets loose. I also want damping if I hit a rock or pothole or another bike's tire - at ANY speed. The HESD isn't on at slower speeds.
C. I want to adjust for conditions and speeds I am running. Adjustable is always better for me.
(Stock, it won't get stiff enough for real serious very high speed headshake.)
D. The damn thing went to full on when I was splitting traffic and needed to make a quick right move. I almost didn't make it because I didn't expect any resistence. That's when I finally pulled it.
I am much happier with the GPR.
