I have been designing and building a Beemer Bobber of the last 8 months and have probably another 8 to 10 months to go. I started with a nice 1977 R100/7. cut the frame in half ,extended the wheel base an additional 6 inches and made it a "hard tail. This bike will have great lines with a "classic" airhead motor. I will post some pictures soon........Macleod
