I downloaded it last year from the movie link of this page. It's not there anymore, the file was huge 165MB (gsxr13-vs-zx12.mpeg).
This is one of the better comparisons I've seen between the Busa and 12R. It's a video of a television show called 2 Wheels down in Australia. A silver 12R and a blue/silver Busa showing top speed runs, stunts and drag strip comparisons.
I have a copy of the .mpeg, but not sure where to post it for download.
