The R69S, R69US, and R69 are motorcycles, fitted with 594 cc boxer twin engines, that were manufactured by BMW in Munich, Germany. ==Production history== From 1955 to 1969, 15,347 of these 594 cc shaft-drive, opposed twin motorcycles were built. The R69 was produced from 1955 to 1960, the R69S was produced from 1960 to 1969,〔Falloon, page 15〕 and the 42 hp R69US was produced from 1968 to 1969.〔Falloon, page 19〕 These models were designed as relatively high powered, high compression sport bikes, although the Earles fork R69 and R69S came with sidecar lugs installed on the frames. These lugs were deleted from the telescopic fork "US" models. The low compression R60/2, produced from 1955 to 1960, was designed primarily for sidecar use, though it was popularly used as a solo bike, along with the 30 hp R60US, which was produced between 1968 and 1969. The sport-oriented R69S, R69US, and R69 succeeded the plunger-framed 1951 to 1955 R68, which had an engine very similar to that in the later R69. The R69US models, with telescopic forks, which were used later on the BMW R-/5 series motorcycles, were introduced in the United States for the 1968 model year and then continued for 1969. Front and rear side reflectors, demanded by the U. S. Department of Transportation, were introduced only for the 1969 model year, along with a DOT sticker that was placed on the rear fender. The previous Earles fork continued to be offered during these years. In June 1962, ''Cycle World'' magazine published a review of the R69S.
