1954 Ariel 995cc Model 4G MkII Square Four For Sale by Auction
In 1937 a total redesign saw the Ariel 'Square Four' re-emerge as the Model 4G, with 995cc overhead-valve engine, making it an even more enticing prospect for sidecarists. Anstey Link plunger rear suspension became an option in 1939 but would not be offered again until 1946 when a telescopic front fork replaced the previous girder type. An exercise in weight shedding saw the cast-iron cylinder head and barrel replaced by alloy components for 1949 on the revised 'Mark I', which was now capable of 90mph-plus. Introduced in 1953, the 'four-pipe' Mark II with redesigned cylinder head elevated the Square Four into the league of genuine 100mph motorcycles. Square Four production, along with that of all other Ariel four-strokes, ceased in 1959. To date, the innovative Ariel Square Four remains unique in motorcycling history; a true 'gentleman's motorcycle', this refined yet characterful machine retains an enthusiastic and loyal following and is highly prized by discerning enthusiasts. Owned by the current vendor since October 2017, this Square Four is offered in need of re-commissioning, or possibly more extensive renovation, and is sold strictly as viewed (the engine turns and the machine would respond well to detailing). Accompanying documentation includes an HMRC letter; starting instructions; and a V5C Registration Certificate.
