Re: Uh?
I've got an 17yo BMW K bike; 4cyl in line, lying on it's side length ways if you didn't know rather then the trad BM-Boxer units. Rumour has it that when BM were tinkering with prototype options they used a Fiat engine .. Apparently BM cars didn't make small enough lumps at the time.
Anyone Fancy a Twin Air lump in a bike frame ??
