The 1955 Ariel 4 G Square Four Mark II showcases Ariel's commitment to innovative engine design. Its 995cc square four engine, producing 45 horsepower at 5500 RPM, delivered a smooth and distinctive riding experience. Reaching a top speed of nearly 100 mph, the Mark II provided competitive performance for its time. Weighing in at 425.5 pounds, it was a substantial machine built for touring. The ergonomics of the Mark II prioritized rider comfort, with an upright riding position suitable for long distances. The 4.23 US gallon fuel tank provided adequate range between refueling stops. The front suspension featured an oil-damped telescopic fork, offering a degree of refinement in handling. Braking was handled by expanding drum brakes, typical for the era. This motorcycle is geared towards vintage motorcycle enthusiasts and collectors who value the unique engineering and classic aesthetics of British motorcycles. It stands as a testament to Ariel's innovation and the riding experience of the 1950s.
