Archive of BMW Motorrad Club Cape (2006 - 2019)

Purely by chance (it was on a German motorcycle forum and I don't speak any German!) I came across a link to this superb document/write-up by Hans Jud on the history and development of BMW Boxer twin motorcycles. Whilst there's a number of books and websites publishing information on the history of BMW motorcycles this is 58 pages of information with many photographs, diagrams, schemtics etc compiled by one individual (enthusiast!) out of personal interest (and for no gain!). Well worth a read (a friend spent many hours translating to English for me!), make sure you're sitting comfortably, as I said before....58 pages ;-)

Enjoy :-)
