750 R17 – 1935

Technical advance

The first BMW 750cc motorcycles went on sale in 1928 — they were the side-valve R62 (78x78mm) and the oversquare (83x68mm) R63 with overhead-valves.

The First BMW with Pressed-Steel Frame ...

In 1929, the R62 was replaced by the R11, which was broadly similar but had a pressed-steel double-cradle frame that started a trend throughout the industry and was used by the majority of manufacturers, especially in Germany. Once again, a side-valve version was paralleled by an overhead-valve model, the R16, with the same bore and stroke as the R63.

... and Telescopic Forks

The major innovation on the two new 750s launched in 1935 — the R12 and R17 — was their hydraulically-damped telescopic forks. It was the first time this type of suspension had appeared on a mass-produced motorcycle. Still with an oversquare engine — more suitable to the high speeds of which an overhead-valve machine was capable — the R17 had practically the same power unit as the earlier R16 but was fitted — like the R12 — with a new four-speed gearbox controlled from the tank by an automobile-type shift lever pivoting directly in a turret on the gearbox lid. It remained in production until 1937. Very expensive — but prestigious — the R17 was the most powerful motorcycle built by BMW until its 600cc R68 of 1952 and the last overhead-valve 750 from the marque up to the R75/5 of 1969.
