BMWR 52 1928 - 1929

　　In 1928, BMW released the R52, a road motorcycle made by the German manufacturer from 1928 to 1929. The model entered the series of R52 that encompasses motorcycles of different displacements.

　　The first model of the R52 series was sold to the general public in 1928 and was part of the trial category. The R52 was meant to be an improved version of the R42, sharing the chassis and various components with the sporty version R57.

　　Compared to the R42, which had a displacement of 494cc, the R52 model suffered a decrease in the displacement department, going to 486cc. This decrease was due to the changed bore/stroke ratio from square measures on the R42 to the long stroke engine on the R52.

　　The power of the R52 remained unchanged, with an output power of 12 hp at 3,400 rpm and a three-speed manual transmission with a dry, single-plate clutch. Unlike rivals who used a chain drive, the R52 got its shaft sealed and no maintenance was required.

　　The 1928 BMW R52 came with standard features such as a plate spring fork, a hard-tail rear suspension, a single saddle, a front drum brake coupled to a block brake in the rear, laced wheels, a large headlamp, full fenders, and a rear luggage rack.

　　In 1929 the production of the BMW R52 ceased after 4,377 units were built, due to the Great Depression.
