BMW R25 (1950-1951) Specs, Performance & Photos

In 1950, BMW released the R25, a replacement for the previous single-cylinder R24. The model featured a welded tubular steel frame that once again permitted the mounting of a sidecar. Also, for protecting the rider from debris, the front fender had in its design a front mudguard in a sweeping shape.

Being reserved for the models with twin-cylinder engines the R25 featured a striking innovation with the plunger rear wheel suspension. The 1950 BMW R25 proved to be very successful at the time, with 23.400 units manufactured.

Even though the R25 was relatively expensive, it met the public’s taste, and together with its R25/2 and R25/3 successors models, over 100,000 units rolled off the Munich production line within six years.

The BMW R25 had equipped a 247cc air-cooled four-stroke single-cylinder engine that developed 12 hp available at 5,600 rpm, working together with a four-speed manual transmission. The 140 kg (308 lbs) weight of the model helped to reach a top speed of 95 kph (58 mph).

The welded tubular steel frame housed a front telescopic fork suspension and a plunger rear suspension, both featuring wire-spoked wheels with a 160 mm drum brake unit front and rear.

As standard features, the model included a sprung single seat, a rear luggage rack, wide handlebars, a large headlamp, a small tail light, and full fenders.
