The BMW R 69S was a air-cooled, four-stroke, boxer twin cylinder, 2 valves per cylinder Classic motorcycle produced by BMW in 1960. Claimed horsepower was 41.97 HP (31.3 KW) @ 7000 RPM.


S version of the BMW R69.


In the early 1950s BMW concentrated on refining what were essentially pre-war designs, but by 1955 was ready with a brace of new machines, the BMW R50 and R69. Of 500cc and 600cc respectively, the newcomers inherited the updated, flat-twin engine introduced on the R51/3 a few years previously but deployed this in all-new cycle parts, the most notable departures from preceding practice being the Earles-type, leading-link front fork and swing-arm rear suspension enclosing the drive-shaft in the right leg - developments first seen on the works racers. A luxury tourer capable of over 100mph, the R69 cost as much as a small family car and sold to discerning enthusiasts for whom expense mattered little when set against the excellence of BMW engineering. The R50/69 were produced until the arrival of the slightly more powerful 'S' versions for 1961. The larger of these, the R69S, produced 42bhp and was good for a top speed of around 110mph. 'Luxury roadster with superb high-speed performance yet docile traffic manners; magnificent steering, roadholding and brakes,' was Motor Cycle magazine's verdict.


Engine[edit]

A 71.1mm bore x 71.1mm stroke result in a displacement of just 594.0 cubic centimeters.

Drive[edit]

The bike has a 4-speed, manual transmission. Power was moderated via the dry, single plate.

Chassis[edit]

It came with a 3.50 - S18 front tire and a 4.00 - S18 rear tire. Stopping was achieved via 200mm drum in the front and a 200mm drum in the rear. The front suspension was a telescopic fork while the rear was equipped with a plunger shocks.
