1959 BMW /2 Conversion

This 1959 R50/2 got a modern heart transplant—a 1973 R75/5 engine with electric start—then someone threw every trick at it: Sport tank, Corbin seat, Hoske mufflers, fresh paint, and 30k freshly rebuilt miles. If you appreciate air-cooled boxer geometry married to actual reliability and rideability, this Frankenstein is the black flag sleeper that costs half what a numbers-matching original would.
