1950 Ariel 998cc Square Four 4G MkI Frame no. CW247 Engine no. RD1363

1950 Ariel 998cc Square Four 4G MkI Registration no. WAS 415 Frame no. CW247 Engine no. RD1363 Designed by Edward Turner, creator of the legendary Triumph Speed Twin, the first Ariel Square Four was shown at the Olympia Motorcycle Show in 1930. Conceived as an overhead-camshaft 500, the model grew to 601cc before a total redesign saw it emerge as the Model 4G, with 995cc overhead-valve engine, in 1937. 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, the revised model, now capable of 90mph-plus, being known as the Mark I. Introduced in 1953, the 'four pipe' MkII 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. Unfortunately little is known of this Square Four's history prior to its acquisition by the vendor in September 2003, since when it has been dry stored. Recommissioning to a greater or lesser extent will be required before the machine returns to the road and thus it is sold strictly as viewed (the engine turns over). Offered with an old-style V5C document.
