Review

The 1951 Ariel 4 G Square Four Mark I presents a unique riding experience with its 995cc square four-cylinder engine. This engine produces a respectable 35 horsepower at 5500 rpm, propelling the motorcycle to a top speed of 90 mph. The four-speed gearbox provides adequate gearing for varied riding conditions. Weighing in at 197 kg, it has a solid feel on the road. The ergonomics suggest a classic touring posture, suitable for covering distances with reasonable comfort. The oil damped telescopic front fork offers a degree of sophistication for its time, aiming to smooth out the road's imperfections. However, the expanding drum brake on the front wheel calls for anticipatory riding and careful modulation. This Ariel targets riders who appreciate the charm and engineering of vintage motorcycles. Its 16-liter fuel tank is smaller than some contemporaries, but still offers a usable range. The 4 G Square Four Mark I appeals to those who value the distinctive character of a classic British motorcycle and are willing to embrace the maintenance and riding style that comes with owning a piece of history.
