Probably not the right spot for this but... I found this site while searching the interweb for information. It has some great old sales brochures on there. This link is for the FZR250, but you can scroll through the others to find what you're looking for. They're in Japanese, but still memorable. Enjoy http://planetjapanblog.blogspot.com.au/2014/02/vintage-japan-brochures-yamaha-fzr-250.html
I saw a few there (in Resources), so I didn't bother linking any others. There are a few on this site I'd never seen before plus a bucketload of other pics and info. Amazing what you find when you use a Japanese search engine.
