Yamaha YZ80 and YZ85 History 1974-2019

These are Yamaha’s YZ80 and YZ85 mini motocrossers from 1974 through 2019. I have put these together over several years of research and I think this is a comprehensive collection of Yamaha’s mini motocrossers. The first link is of pictures of all the bikes, but I am also including the video version I did last year for my YouTube channel.
