298770

Up for auction is my dad's cherished 1972 BMW R75/5 in blue! First off i must say this is one of the nicest well kept R75/5 i have ever seen! Climate controlled garage kept,babied, and regularly exercised to keep it in shape. This low mileage BMW is almost completely original and in superb condition as you can see in the photos! Starts, runs,drives, and stops great every time! Little updating but have kept all original stock parts to keep it complete. Tons of receipts and paperwork for the bike. My dad has cared for this bike for many years and i would not have a problem jumping on it and driving anywhere in the lower 48 states and needs nothing so you can bid with confidence. Please feel free to ask any questions. Now for some technical info..... The “/5” series of BMW's offered a 12 volt electrical system, electric starters as well as the retained kick starter, telescopic forks, and improved brakes. The sidecar was no longer factored into the design, allowing for better handling. BMW also introduced with this model non-metallic fenders and tail light housings for the first time. The use of plastic and other non-metallic materials resulted in a motorcycle weighing only 463 lb (210 kg). Model year 1972 saw the introduction of the 15 L (3.3 imp gal; 4.0 US gal) “toaster” tank with chrome side panels, so named because of its resemblance to a kitchen toaster. 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 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 R75/5 comes with 32 mm Bing CV (Constant Vacuum/constant depression) type carburetors. 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. The /5 models came with an electric starter, but the new series (along with the first few of the next series, the /6) retained the outward swinging kickstart connected to the input shaft on the back of a four-speed gearbox similar to the one on the /2..
