the GPR is a good damper. I had one on my R6 and it made a noticeable difference. However, I would make sure your suspension is set up for you as well. If you bought the bike new (or even used) and have never had the suspension set up, then you'll be surprised at the difference with a properly tuned suspension. There are many books on the subject, one in particular is 101 sportbike projects. Also, when buying parts and accessories, check out Speedwerks.com. They are really nice, helpful folks.
