Or, things you discover when nothing much else to do.
This is a 1958
BMW R50. If you have o
ne in this condition it’s worth a not insignificant sum.
Like many (but by no means all) a BMW bike before and since it has a flat twin with its cylinders arranged horizontally and therefore with a longitudinal crank.. Attached to this is a longitudinal gearbox. Not by coincidence this makes the company’s traditional shaft drive easy to arrange.
As with all BMWs up to the early 1970s it has a kick start. But the kick start is not as others are.
Usually a bike has a transverse crank and to go with that a transverse gearbox. Logically then the kick start is transverse and so its pedal turns through a longitudinal arc. Look from above and it goes back wards and forwards.
Not a BM W’s. Equally logically the kick start operates on a longitudinal shaft and so its pedal turns through a transverse arc. Look from above and it goes in and out rather than backwards and forwards, like so:
Not many know that.
HFV has no HFV. But somehow has 2 motorcycles
