By all means, take it if you've got the desire. To set your mind at ease, here are some shots and a video clip of my 608# CBR-1000F at the track. It's a '90 with 90,000 miles on it in these photos and clip. All original, too. Running in the "fast" group at a Sportbike Track Time event at Beaverun near Pittsburgh.
The video even sports a slide at the end. Sorry about the quality. Also, the audio lags behind the video, getting progressively worse towards the end.
