1943 R75 3x2

1943 BMW R75 3x2

This BMW with Steib sidecar had originally been designed to tow a light gun, but the weight on the tow-bar lifted the front wheel off the ground. Armed with a mobile machine gun, the BMW was a rugged, reliable go-anywhere vehicle. Expensive to build, its cost was double of the Porsche designed VW (Jeep-like) vehicle, even so, 16,500 machines were built and remained in service throughout the war. The palm tree insignia indicates that this machine was part of Rommel's Afrika Korps. This bike was built to the same specifications as the Zundapp KS750.

</sgallery> All slash-5 models have air-cooled, four-cycle, opposed-twin (boxer) engines with hemispherical combustion chambers. Their engine housings are one-piece tunnels housings. The camshaft, driven by a duplex chain, runs at half of the engine speed and is located below the crankshaft. This is the reverse arrangement from the /2 models and allows gravity to assist the delivery of oil to 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. The R75/5 comes with 32 mm Bing CV (Constant Vacuum/constant depression) type carburetors. As in all BMWs to the time, the clutch is a single-disk dry clutch. The slash-5s have four-speed transmissions and come with kick-starters as well as electric starters. The kick starters are less sturdy than on previous models and are a frequent point of failure, most often due to incorrect kick starting technique. They were intended for emergency use in the incident of an electrical failure. When properly tuned, a slash-5 can be started by operating the kick start lever with the hand, requiring very little force to start the engine. [1] 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 slash-2 models, the slash-5 models are equipped with telescopic front forks, 12-volt alternator and electrics, and standard tachometer and turn signals.
