I got mine installed Thursday (it took me about an hour) and went out for a 60 mile ride yesterday. The roads finally dried out and the temp hit 40. The bike did seem more stable than before on fast sweepers after hitting a bump. Also, there seemed to be a bit more vibration at low rpm's, but at cruise speed around 3,000 rpm and above it seemed to be smoother than before. Seems to be a good addition.
