This 1962 R50S is one of the more sought after BMW bikes because BMW built so few and for only 2 years. The total production is in the 1,400+ range. Many of these bikes were used for racing so the engines were separated from the matching number frame and therefore lost much of their collectability.
The frame has been striped to bare metal and zinc primed and powder coated along with the swing arms and center stand. The painted parts, fenders and tank were painted with single stage black and pin stripped. The crank shaft has been rebuilt to factory specs and the engine fitted with all new seals and bearings along with the correct rear spherical bearing. Transmission and final drive were also totally rebuilt. Weinmann rims were professionally polished and laced with stainless steel spokes, trued and new Heidenau tires and tubes mounted. Wheel bearings are new and properly pre-loaded and lubricated with new seals.
Electrics are new, main harness, switch harness’, switches, Hella bar end signals and a 12 volt conversion upgrade to the charging system.
