In 1951, at the Amsterdam Salon, BMW presented the R67, the first post-war motorcycle with a displacement of 600cc. The BMW R67 had smooth running and handling but received criticism that mainly referred to the front brake that lacked power when the motorcycle was ridden with the sidecar attached.
BMW responded to the criticism with a revised version of the R67 presented in December 1951 under the R67/2 name. The bike was visually unchanged, but the engineers installed a more effective duplex brake on the front wheel.
The engine had a higher compression and two hp more than the previous motorcycle. With a displacement of 594cc, the air-cooled four-stroke twin-cylinder boxer engine had a power output of 28 hp at 5,600 rpm. Together with a four-speed manual transmission and a weight of 192 kg (423 lbs), the power sent to the rear wheel pushed the bike to a top speed of 145 kph (89 mph). With an original BMW sidecar attached, the bike weighed 320 kg (705 lbs).
Like the R67, the R67/2 model was a popular motorcycle that consolidated BMW’s reputation as a sophisticated touring machine manufacturer.
Standard fittings that came with the bike included wire-spoked wheels, full fenders, a rear luggage rack, a round headlight, a sprung single seat, a dual exhaust system, a small taillight, and a center stand.
