The Norton Commando, a motorcycle produced by the Norton Villiers company between 1967 and 1977, is a legendary machine that cemented its place in motorcycle history. The 750 Commando, first launched in 1967, marked a significant departure from previous Nortons. It featured a redesigned, more powerful 745 cc parallel-twin engine, coupled with a revolutionary swing-arm rear suspension. This new design, dubbed the "Isolastic" system, drastically improved ride quality and handling, setting a benchmark for the era. Subsequent models, like the 750 Commando Combat, further enhanced the Commando's capabilities with the addition of military-inspired features like a high-mounted exhaust, and a rugged, utilitarian aesthetic. The evolution of the Commando continued with the introduction of the 850 Commando in 1972. Featuring a larger 828 cc engine, the Mark II, Mark IIA, and Mark III models, produced between 1972 and 1977, saw further refinements to the engine, suspension, and styling. Despite facing stiff competition from Japanese manufacturers, the Norton Commando continued to earn accolades for its performance and charisma. The Commando's iconic status rests on its distinctive, powerful engine, its innovative Isolastic suspension, and its timeless design. It remains a sought-after classic, appealing to both collectors and enthusiasts who appreciate its engineering prowess and historical significance.
