The BMW R11 Series 4 was a two cylinder boxer, four-stroke Classic motorcycle produced by BMW between 1929 and 1934. It could reach a top speed of 68 mph (110 km/h). Claimed horsepower was 17.57 HP (13.1 KW) @ 3400 RPM.
History[edit | edit source]
Shortly after venturing into car manufacture for the first time by acquiring the Dixi works at Eisenach, BMW introduced a major innovation to its motorcycle range in 1929. The transversely mounted 'flat-twin' engine was already a BMW trademark but for the first time it was installed in a pressed-steel frame, the first model to incorporate this landmark of motorcycle design being the 740cc R11. BMW's relatively vibration-free engine was already a byword for smoothness and refinement, and this, coupled to a three-speed shaft-drive transmission, made the R11 sidevalve one of the finest touring motorcycles of its day. Progressively improved, the R11 was built in five series up to 1934. This R11 displays a total of only 4 kilometres on the odometer, which, presumably, is the distance covered since restoration.
Engine[edit | edit source]
The engine was a air cooled two cylinder boxer, four-stroke. A 78.0mm bore x 78.0mm stroke result in a displacement of just 745.0 cubic centimeters. Fuel was supplied via a sidevalves.
Drive[edit | edit source]
The bike has a 3-speed transmission. Power was moderated via the two plates-dry.
Chassis[edit | edit source]
It came with a 3.50-26.00 front tire and a 3.50-26.00 rear tire. Stopping was achieved via expanding brake (drum brake) in the front and a 37mm cardan brake in the rear. The front suspension was a plate springe while the rear was equipped with a rigid. The R11 Series 4 was fitted with a 3.7 Gallon (14.00 Liters) fuel tank. The wheelbase was 54.33 inches (1380 mm) long.
1929 - 1934 BMW R 11[edit | edit source]
The 1929 BMW R 11 sports an air-cooled, four-stroke, 745cc, twin cylinder powerplant paired to a three-speed manual transmission and can produce a claimed 20 horsepower at 4400 rpm. It comes with a plate spring front suspension, a rigid rear suspension with a sprung saddle, a dual exhaust system, a rear luggage rack, laced wheels, a round headlamp and a dry, single plate clutch.
