Gimson, produced in Spain from 1954 to 1982, was a Girona-based manufacturer known for its lightweight motorcycles, mopeds, and small off-road machines. The brand gained recognition for models such as the Polaris series, particularly in trial, cross, and sport variants, typically in the 49cc to 125cc range. Gimson motorcycles were characterized by simple two-stroke engines, durability, and accessibility, making them popular for both everyday use and amateur competition. The company ceased production in the early 1980s, remaining a representative name in Spanish motorcycling history.
