And Who or What
is Barrington Motor Works, LLC?

Barrington Motor Works -Christopher and Barbara Betjemann

After more than forty years of motorcycle riding and wrenching, and more than twenty years of the restoration and construction of our personal BMW motorcycles, we, Christopher and Barbara Betjemann established Barrington Motor Works, LLC in 1999 to share what we had learned and knew about the vintage BMW motorcycle with other BMW vintage motorcycle enthusiasts.

Christopher, a former emergency physician who was now retired, needed something to direct his considerable energies and abilities toward. And Barbara, a painter and Christopher's lifelong partner, shared that dream. Over the years of restoration of our own BMW motorcycles and the creation of a number of vintage BMW specials we had not only acquired and developed a significant armamentarium of skills, but had also established friendships and business relationships with many talented and experienced individuals both here and in Europe who, like us, wanted to contribute to the vintage BMW motorcycle community.

Although we enjoy the restoration of vintage BMW solo and sidecar machines, we also take great interest in the building of both vintage BMW race machines and cafe machines for the street.

Having said the above, join us and enjoy our website, seeing photographic and written essays about some of the machines that have passed through our shop, as well as learning about some of the services which we can provide to you and others in the vintage BMW motorcycle community.

Except by prior arrangement, our shop is closed all weekends. Shop hours are typically Monday through Thursday 9:00 AM to 5:00 PM and Fridays 9:00AM to 4:00PM (all times Eastern Time Zone). We frequently deviate from these hours for vintage meets, days at the racetrack and pleasure riding so it is best to email or call ahead before planning a visit to the shop.

Latest Updates

Updated: July 31, 2016
Our newest vintage BMW motorcycle manual, The Barrington Motor Works BMW R26-27 Motorcycle Restoration and Service Manual is rapidly nearing completion.  The R26-27 manual will be similar in construction and size to our other manuals mentioned below.
The restorations of a traditional Avus Black R26 and a Dover White R27 with an original parade tank to confirm the clarity and flow of our writing, as well as to take the remaining needed photographs have been completed.
Three quarters of the manual is now in the hands of our graphic designer who is now waiting for the delivery of the balance of the manual. We anticipate being able to review the first three quarters of the completed manual within the first week of August.
When the fully designed manual is electronically transmitted to our printer we will offer the manual at a pre-publication discount as we have done with our other manuals. The first 100 such manuals will be both numbered and signed.
Upon the completion of the R26-27 manual and the documentation of both machines, the Avus Black R26 and Dover White R27 with original parade tank will be available for purchase.  Both machines have had their 100 mile checkout rides and will be listed in the for sale section of this website within days.
