Having previously had a nice tank slapper after hitting a pothole on the freeway on my GSXR at freeway speeds that I was somehow able to ride out of, I am a fan of steering stabilizers. I definitely want to get one for my ZSM. Are the Scotts and GPR the main ones available? My understanding is that the Scotts only damps from center out whereas the GPR also damps out to center as well. For twisties, tracks, freeway, and some dirt excursions, which is recommended?
