You're welcome, Laitch.
When they get to the K, they leave out one of my favorite details about BMW's decision to go with the inline 4.
With all their experience (and brand identity) with boxers, you'd think they would have gone for a water-cooled boxer 4, right? But they were also committed to creating a motorcycle unlike any other, and Honda already had the Gold Wing on the market. (And the Gold Wing was shaft drive, too . . . .) My understanding of the story is: if not for the Gold Wing, our K's would be boxers.
