The 1954 Ariel 4 G Square Four Mark II represents a significant evolution in Ariel's distinctive motorcycle design. Its 995cc square four engine, producing 45 horsepower at 5500 RPM, offered a unique and smooth power delivery. The motorcycle reached a top speed approaching 100 mph, making it a capable machine for its time. Weighing in at 425.5 pounds, it was built with touring in mind. The ergonomics of the Mark II focused on rider comfort, featuring an upright riding position suitable for long distances. The 4.23 US gallon fuel tank allowed for reasonable range between refueling. The front suspension utilized an oil-damped telescopic fork, providing improved handling compared to earlier designs. Braking was achieved with expanding drum brakes, standard for motorcycles of that era. This model is best suited for vintage motorcycle enthusiasts and collectors who admire the unique engineering and classic styling of British motorcycles. It offers a tangible connection to the motorcycling heritage of the 1950s.
