Great collection if you are interested in Brit bikes.
Have you ever toured the back warehouse at Michael’s Powersports? Michael’s has one of almost every MX and enduro bike from the 70s through the 90s. It is a VERY cool collection. A few of the bikes are on the main showroom floor, I think the last time I was there I saw a CR480, Maico 490 and a HD MT500 dual sport (with rifle case).
