The BMW R60/6, R75/6, R90/6 and the sport model BMW R90S form a range of boxer twin motorcycles that were manufactured in Berlin , Germany, by BMW from 1974 to 1976. [1] The "slash six" models departed from the earlier "slash five" slightly. First, the smallest displacement changed from 500cc to 600cc. A sport model was offered, as were disc brakes (front only) for the first time. Additionally, the tank design was changed to remove the chrome trim panels (rubber knee pads were added instead), and the gauge pod was moved from the headlight housing to its own assembly over the housing.

Like the preceding /5 bikes, the /6 models are air-cooled, four-stroke, opposed-twin (boxer) engines with hemispherical combustion chambers . The engine is built around a one-piece tunnel crank-case. The camshaft is driven by a duplex chain and is located below the crankshaft. Valves are actuated by the camshaft through hardened followers, push rods, and rocker arms. The same base 247 engine was used for these motorcycles.

Final drive is by shaft, running from the transmission by universal joint to an oil bath within the right rear swing arm and connecting to a bevel gear and ring gear on the other end. Like the /5 models, the /6 models are equipped with telescopic front forks , 12-volt alternator and electrics, and standard tachometer and turn signals.

The Monza Blue R75/6 offered here is in excellent condition with a low 28,000 miles. The tires are new Continental Twins, the same type of tires that came on the /6 series from the factory. Blue Moon Cycle completed a full 10K service and we replaced the steering head bearings, something that is often overlooked on used motorcycles. This bike runs and rides like the day it left the factory. I bought my first BMW in 1976 and I have been riding and wrenching on BMWs ever since. I know when a BMW performs right and this one is right.
