I was just browsing the dirtbike section of Georgia Offroad and stumbled onto a picture of a 1987 YZM 500. I never knew this bike ever existed. It looks like a pretty sweet bike. Anyone have any experience with this white beauty? Heres the pic: http://www.georgiaoffroad.com/dirtbikes/yamaha/yzm/87yzm500.jpg
Look closer guys and you'll see that subframe and airbox are all one piece in design, its like a stressed member. What they call that monoque something like that. Honda had it on thier works bike back in the early 80's, hey didn't yamaha get the body work design for the 88 yz250 from this bike? I bet that bike was nightmare to make back then.
