The 1951 MY BMW R 51/3 has received an upgrade in the engine department, namely, the two chain-driven camshafts that were found on the R 51/2 were replaced by a single central camshaft driven by gearwheels from the crankshaft. In all other aspects, it is mainly the same machine as its predecessor.
It comes with a front telescopic fork, dual plunger shocks as a rear suspension, a drum braking system, full fenders, a large, round headlight, a single seat, a rear luggage rack, a dual exhaust system, a blacked-out steel frame, a small tail light and a dry, single plate clutch.
