Andy Hertzfeld[*] says:
In the spring of 1984, right about the time that I left Apple, the lobby began to fill up with more interesting artifacts, purchased by Steve Jobs on his various travels. There was an outrageously expensive Bosendorfer piano that was soon accompanied by a BMW motorcycle, on display as examples of exquisite craftmanship, although it was rumored that Steve purchased them to impress the industrial designer that he was enamored with at the time, Hartmut Esslinger, whose firm, Frog Design, designed the case of the Apple IIc.
I think I read in one of the various Apple related biographies that the bike in the lobby was a K bike.
[*] As a pre-teen I disassembled very elegant 6502 assembly code from Andy Hertzfeld before I knew who he was.
