Vehicle Information
BMW R50 Motorcycle - Street (1955-1973)
The BMW R50 series, produced from 1955 to 1973, represents a significant era for the German manufacturer's motorcycles. These models, primarily powered by a 494 cc flat-twin engine, were renowned for their robust engineering and versatility, serving both touring enthusiasts and police forces. The original R50 (1955-1960) introduced a full-swing chassis with Earles front forks. A notable evolution came with the R50/2 (1960-1969), featuring internal engine improvements for enhanced durability. For performance-oriented riders, the R50S (1960-1962) offered increased horsepower, though its production was brief due to reliability challenges. The R50 US (1967-1969), exclusive to the American market, brought telescopic front forks and a distinct aesthetic. The series culminated with the R50/5 (1969-1973), a major redesign that introduced a new lightweight frame, modern telescopic forks, and an optional electric starter, marking a transition to a more contemporary design philosophy.
