BMW motorcycles
single-cylinder models. In 1967, BMW offered the last of these, the BMW R27 [1].
Most of BMW’s offerings were still designed to be used with sidecars. By this time sidecars were no longer a consideration of most riders; people were interested in sportier motorcycles. The R50/2, R60/2, and R69S marked the end of sidecar-capable BMWs.
In 1970 BMW introduced an entirely revamped product line of 500, 600 and 750 cc displacement models, the R50/5, R60/5, and R75/5 [2] respectively. The engines were a complete redesign from the older models, producing more power and including electric starting (although the kick-starting feature was still included). The “/5″ models were short-lived, however, being replaced by another new product line in 1974. These models were the R60/6, R75/6 and the R90/6. In 1975 a supersport model, the BMW R90S [3], was introduced. The R90S immediately earned the well deserved title of the best supersport machine available.
Each of the last few years (2004, 2005, 2006) appear to be banner years for BMW. On 25 September 2004, BMW globally launched a radically redesigned K Series motorcycle, the K1200S, containing an all new in-line four-cylinder, liquid-cooled engine featuring 123 kilowatts (167 bhp).[6] The K1200S was primarily designed as a super sport motorcycle, albeit larger and heavier than the closest Japanese competitors. A K1200S set a land speed record for production bikes in its class at the Bonneville Salt Flats, exceeding 174 miles per hour (280 km/h).
In addition to the launch of K1200S, in 2006 BMW has also launched the K1200R “naked” roadster, and the K1200GT sports tourer. All three new K-Series motorcycles are based on the new in-line four-cylinder engine, with varying degrees of power.
In 2007 BMW added the K1200R Sport[4], a semi-faired sports touring version of the K1200R
