Yamaha AT90/AT90D Parts List, a two-volume set of parts lists for each minor model. This is a genuine manufacturer's product issued in 1968. It's a valuable, new, unused item that was stored at a parts store, but there is some discoloration and minor scuffing on the cover and pages due to storage. I purchased this intending to acquire an AT90, but I'm selling it because I've changed vehicles. Thank you very much.
