My brother owns an XB12R, but we haven't had much opportunity to ride it because of the weather. Also, he injured his shoulder at work and had to have surgery, which means he REALLY can't ride, regardless of weather. I'm probably going to have to break it in for him, so I'll let you know how it feels compared to an R6. He and I are also talking about swapping bikes at a track day sometime, just to see the differences.
Oh, and he has a red one, but HATES the gold on the red bike. He had silver wheels put on it when he bought it, then he swapped out the windscreen and had some custom emblems made. We'll have to get some pics posted up here for you all to see.
