The rear seat on my '11 CBR600RR was absolutely brutal for my finacee to ride, like literally tears after a half hour riding brutal. We started shoppping around for different seats and found only rider seats being addressed in the aftermarket and custom seat building was looking around 2 weeks turn around and as much as $200 for something that "may" help. We bought this as a trial and instantly noticed a huge difference in comfort and now several hours in the saddle are not a painful issue and she had no next day pain like before. The pad is small, but perfectly sized for a sportbike rear seat, for the money it's well worth it; the lack of nagging alone makes it worth it at twice the price!!!! We definitely will not ride without it.
This narrow pad does NOT solve the actual problem. The seat on the back of my bike is simply too narrow. The girlfriend, 5'7", 125 lb, and size 2 found that even with the pad, all her weight was concentrated on her tailbone. The WIDTH of the seat, not the material was the issue. I have the Xtra large gel pad for the front, #I'm 6'00", 270 and NOT a size 2# and it DOES seem to help me. But, we cannot reccomend this for a lady on the back, regardless of size.
