There's one for sale here:
Yamaha motorcycle for sale : 1999 Yamaha R7 for sale
Awesome... $26,500 though!! I've always thought this was a really cool bike so I look them up from time to time and came across this. I wish Yamaha would bring this bike back, with the new R-series looks.... I keep thinking about a Gixxer 750, but, it's a Gixxer... hehe
These were only made a few years, in homologation numbers (500 I think) for racing. To find one that wasnt raced is very hard.
