Ariel Square 4 Four 1000cc 1957

Ariel Square 4 1000cc 1957. In very nice condition looking to be an older restoration with 6062 miles on the clock. Built with stainless rims and spokes. Looks to retain its original registration number VAS 511. This is the desirable 4 piper example which are getting harder to find compared to the 2 in to 2 models. Starts up and runs great. A fine example at a very good price !

History: Designed by Edward Turner, creator of the trend-setting 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' 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 charismatic machine retains an enthusiastic and loyal following and is highly prized by discerning enthusiasts.

"This big motorcycle with its mighty 61 cubic inch overhead valve engine handles like a lightweight - goes like a bomb! In a road test report "Cycle" Magazine says: "Incredible! - the standard Ariel Four in full road trim repeatedly ran the ¼ mile drag in 12.9 seconds!" - Treat yourself to a new sensation in motorcycling - ride the Ariel Four!"
