1970 R60/5 BMW. This item was owned by my dad for the last 12 years. It was driven little and maintained. Previous owner was know to be meticulous. This bike starts well. idles well. runs well. shifts well. It has no mechanical issues and runs as I would expect. The valves were set in the last 100 miles. It may drip gas from the carbs if the gas is not shut off at the tank. like most of bikes of that era. It looks like it may have been repainted on the tank and fenders. Everything works and I have the ignition key and the seat lock key. The air pump mounted on the fame is under the seat as well. Please see all the pictures for any paint nicks. There is nothing that jumps out every time I look at the bike. https://www. youtube. com/watch?v=4hd-ILpX6g0 for a video of the engine runningFor the 1970 model year. BMW launched three new models having engine capacities of 500 cc (R50/5). 600 cc (R60/5). and 750 cc (R75/5). The /5 series was the first series to be manufactured completely in Berlin. as by 1969 all of Munich's production capacity was needed for automobiles. "Berlin with its well-trained workforce was an obvious choice. So in 1969 the Berlin Plant started production of the all-new BMW /5 Series. a completely new design and construction following a modular principle all the way from the suspension to the flat-twin power unit. [2] By the 1960s. motorcycles as a form of "cheap transport" were being abandoned by post-war consumers who could now afford a car; but the motorcycle market was revolutionised by a new kind of customer who wanted a bike for fun and recreation. Accordingly. production at BMW Plant Berlin began to increase rapidly. In 1970 no less than 12. 87 units came off the production line and by July 1973. when the /5 model series reached the end production. a significant volume of 68. 56 motorcycles had left the Berlin Plant. production increasing five-fold within just three years. Another highlight celebrated at the time[when?] was the completion of the 500. 00th BMW motorcycle in the history of the company. [2] The /5 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 (unlike the /2 series which had the gear-driven camshaft above the crank). This reversed arrangement improves ground clearance for the same center of gravity and assists lubrication of the camshaft. Valves are actuated by the camshaft through hardened followers. push rods. and rocker arms. The 500 cc and 600 cc models are equipped with Bing slide-type carburetors with 26 mm throats. As in all BMW motorcycles at the time. the clutch is a single-disk dry clutch. 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. Unlike the /2 models (with the exception of the 1969 R69US). the /5 models are equipped with telescopic front forks. 12-volt alternator and electrics. and standard tachometer and turn signals.
