BMW R25/3 1953 250cc One Cylinder


BMW’s first new post-war model was a single-cylinder design – the 250cc R24 – which arrived in 1948 looking pretty much like the pre-war R23 but producing an additional 2bhp.

It was superseded in 1950 by the R25, which featured plunger rear suspension but was otherwise very similar. An improved R25/2 version was introduced during 1951 incorporating a stronger crankshaft and minor revisions to the front mudguard stays and seat springing.

Built between 1953 and 1956, the final R25 variant – R25/3 – featured a new telescopic front fork, full-width alloy hubs and alloy wheel rims as the principal upgrades. This 1953 BMW R25/3 has been restored some years ago and runs well.


The R25/3 was an all-around better motorcycle, nothing radical but with slightly more power and improved suspension. The fork now had hydraulic damping, with a manual steering damper up at the steering head. The gas tank was redesigned, with a lockable toolbox built into the side—more aesthetic than the previous model’s top-of-tank toolbox. Model: R25/3. Year: 1953. Displacement: 247 cc.
