|Capacities & Measurements|
In an era when motorcycles still closely resembled the bicycles they derived from, the purpose designed and built R32, with its double loop frame and shaft drive really stood out from the crowd. Even though BMW had already been building proprietary motors for half a dozen motorcycle producers for a few years, their decision to put the cylinders across the frame made an existing concept fresh. Introduced at the Berlin Motor Salon, the first units didn't appear until late in 1923.
