The gb covers arrived, and they look really good. Having said that, I don't think they are a huge improvement over the rg covers. The th set does have the small cover, on the right side of the bike and the rg does not. Probably no big deal. If that ever hit, your so screwed it really does not matter.
This set does have "z1000sx" molded into the plastic, so its not as if it was designed for the other bikes. Overall, I'm pleased. If these score an 8, I'd have to give the rg a 7...Damn good, just not up to this level.
