In the time that I watched, I saw a 78 750F go for $2750, a 76 750K for $6000, and a 75 750K with original pipes for $7500. In general, anything from the 70's or later was getting around 5K, stuff from the 50's and earlier started at 20K. Seemed to be a lot of old Indians with sidecars, Triumphs, and Harleys. Also, surprisingly, a lot of old motocross and enduro bikes, which are apparently a thing now.
