Review

The 1921 Excelsior 20 R represents a significant piece of early motorcycle engineering. Its 974cc (59.43 cubic inches) engine delivered what was considered substantial power for the time, likely characterized by strong low-end torque. The riding experience would have been defined by the engine's raw power and the mechanical sounds of the era. Featuring a trailing link front suspension, the Excelsior 20 R's ride quality would have been distinct from modern motorcycles. This system was designed to absorb bumps and irregularities in the road, offering a more comfortable ride on the less-than-perfect surfaces common at the time. The ergonomics would likely be upright, prioritizing rider comfort over aggressive handling. This machine would primarily appeal to collectors and enthusiasts of vintage motorcycles. It's a chance to own and experience a piece of motorcycling history, offering a tangible connection to the past and a unique riding experience unlike anything available today.
