BMW's first new post-war model, the 250cc BMW R24, arrived in 1948 looking pretty much like the pre-war BMW R23 but producing an additional 2bhp. In mid-1950 the R24 was superseded by the R25, which featured plunger rear suspension but was otherwise very similar.


The engine was a air cooled single cylinder, four-stroke. A 68.0mm bore x 68.0mm stroke result in a displacement of just 247.0 cubic centimeters. Fuel was supplied via a overhead valves (ohv).


The bike has a 4-speed transmission. Power was moderated via the single plate dry-cable operated.


It came with a 2.99-19 front tire and a 2.99-19 rear tire. Stopping was achieved via expanding brake (drum brake) in the front and a expanding brake (drum brake) in the rear.
