I came across this thread on another international forum and thought it worth to share here.
This is a motorcycle museum in the USA where they keep up to 600 bikes on display, old models, and they keep rotating the models time to time. The total collection is around 1200 bikes with over 200 makes from 20 countries, simply fabulous(A) The museum restores many of the bikes itself, and any model you may place your finger on can be brought to the running condition within one hour.
