My Old Man, god rest his soul, bought a Cossack which was the "Lada" of motorbikes in that it was the Russian version of the older BMW R71 and sidecar which was a German military bike. To say it made a throaty racket was an understatement! It served its purpose admirably as I recall and didn't seem to break down as such although it was regularly in bits in the kitchen and garden. Used to love going out on it mostly in the sidecar with my brother but occasionally on the pillion for a treat.
