Ariel Square Four MK II, A Rider Quality Example Made To Be Enjoyed

Enjoy a piece of British motorcycling heritage with this 1958 Ariel Square Four Mk II, one of the most distinctive and refined motorcycles of its era. At the heart of the machine is the 997cc square four engine, featuring two transverse crankshafts, which delivers smooth, linear power with a character all its own. The 4-speed Burman gearbox provides an engaging, connected ride, and for those willing to open it up, the Square Four was even claimed to reach over 100 mph, a remarkable feat for a bike of this period.

This is a rider-quality example, with 10,197 miles reflecting a life enjoyed rather than over-restored perfection. The upright seating position and classic ergonomics make it comfortable for longer rides, while the plunger-style rear suspension and telescopic front fork provide the authentic handling and feel that enthusiasts love.

Finished in gloss Ariel Black, the bike retains its twin exhausts with the unmistakable growl of a Square Four, along with period-correct Lucas lighting and Smiths instruments, keeping it fully authentic. Perfect for weekend outings, classic rallies, or open-road adventures, owning this bike is about riding a piece of history with personality and soul.
