1957 Other Makes Ariel

NML668

1957 Ariel Square Four Engine number: NML668 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 re-designed 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. This example dates from the penultimate season of 1957 production. Resurrected from long-term storage, the bike was delivered to marque expert A.J. Lewis, who rebuilt the engine. Trailblazer Hall of Fame inductee, A.J. hailed from the famed Johnson Motors, Ariel and Triumph dealer of Los Angeles. He worked on their Daytona race team as well as the shop, before opening his own shops specializing in the increasingly popular Ariel. He worked continuously until his death in 2009, and it is believed that this motor is one of his last. Covering only 1000 miles since full rebuild, it still runs strong with good compression and power. Cycle parts were “gone through” so the bike handles well and stops as well as 55 year old British bike technology will stop. The electrical system works well, but the wiring harness is untidy. It has non-original fenders for an old-school bobber look, as well as the seat. For restoration to factory original, parts are readily available from Draganfly.com and a very active owners club. The paint is fairly weak. Frame feels straight and true and there is no indication the bike has had any accidents. This is good running/riding example of a rapidly appreciating classic, with the most costly part already restored by about the best in the business, which can never be repeated. As the “car guys” get in to the motorcycle hobby, the Ariel Square Four is on everyone’s list together with a Vincent, Brough, etc. This bike can be ridden and enjoyed as is, and restored as you go. As a fully restored bike, I would expect to see this example go for $22k+, considering the provenance.
