The Allen Motorsports Collection includes examples of important open wheel racing cars as well as some of the finest post-war British motorcycles, a selection of famous Harley-Davidson racing and sports machines, several European bikes and some of the best machinery to leave Japan.
 
The facility has two levels with motorcycles on the second viewing level and cars below. Motorcycles are raised through the ceiling via a hydraulic lift. The museum has an extensive collection of tools in US and Metric configuration. While some restoration work has been done at the facility, most of the space is currently occupied by the collection.
 
Mr Allen's office occupies a corner of the museum.

The Allen Motorsports Collection is located outside of Boston, Massachusetts and is private. We regret that we cannot accommodate visitors.
