The '''[[BMW]] | The '''[[BMW]] R17''' was a two cylinder boxer, [[four-stroke]] standard produced by [[BMW]] between 1935 and 1937. It could reach a top speed of 87 mph (140 km/h). Claimed [[horsepower]] was 32.32 HP (24.1 KW) @ 4500 RPM. | ||

Having broken fresh ground with the launch of the pressed-steel framed [[BMW R11|R11]] in 1930, [[BMW|BMW]] followed that up with the introduction of an hydraulically-damped telescopic front fork on the [[BMW R12|BM R12]] and [[BMW R17|BMW R17]] models, which were also notable as the first BMWs to have a four-speed gearbox. First seen at the Berlin Motor Show in February 1935, the newcomers were otherwise virtually unchanged from their R11 and R16 predecessors apart from a strengthened crankshaft. The sporting, twin-carburettor, overhead-valve R17 produced 33bhp at 5,000rpm and would be BMW's most powerful production roadster until the introduction of the [[BMW R68|BMW R68]] in 1952. It was priced at 2,040 Reichsmarks, making the R17 the most expensive German motorcycle of its day. Only 436 were produced between 1935 and 1937 and today this rare and exclusive model is one of the most sought after of pre-war BMW motorcycles. | Having broken fresh ground with the launch of the pressed-steel framed [[BMW R11|R11]] in 1930, [[BMW|BMW]] followed that up with the introduction of an hydraulically-damped telescopic front fork on the [[BMW R12|BM R12]] and [[BMW R17|BMW R17]] models, which were also notable as the first BMWs to have a four-speed gearbox.

==Engine== | |||
The engine was a [[air cooled]] two cylinder boxer, four-stroke. A 83.0mm [[bore]] x 68.0mm [[stroke]] result in a [[displacement]] of just 736.0 cubic centimeters. Fuel was supplied via a overhead valves (ohv). | |||
==Drive== | |||
The bike has a 4-speed transmission. Power was moderated via the dry-multiplate-cable operated. | |||
==Chassis== | |||
It came with a 3.5-19 front [[tire]] and a 3.5-19 rear tire. Stopping was achieved via expanding brake (drum brake) in the front and a expanding brake (drum brake) in the rear. The front suspension was a cartridge while the rear was equipped with a rigid. The R17 was fitted with a 3.7 Gallon (14.00 Liters) fuel tank. The wheelbase was 54.33 inches (1380 mm) long. | |||
