c.1934 Ariel 600cc Model 4F Square Four Project
Registration no. not registered
Frame no. Y7690
Engine no. UA198
Designed by the legendary Edward Turner, the Ariel Square Four was first shown at Olympia in 1930. Unique at the time of its introduction, the 'Squariel', as it was swiftly dubbed, featured a single block of four cylinders and twin geared-together crankshafts with pistons phased at 180 degrees. The crankcase was split horizontally, unusually for a motorcycle engine of the period, while the vertical valves were operated by a single overhead camshaft. Although launched as a '500', the Squariel was soon enlarged to 601cc with an eye on the important sidecar market, this 4F/6 version being made available for the 1932 model year. The '500' was dropped after 1932 but the '600' continued until the end of 1936, its place being taken by the totally redesigned Model 4G, with 995cc overhead-valve engine. The '600' reappeared for 1939 as the 4F, redesigned along the lines of its larger sibling, but did not resume production after the war.

This dismantled Square Four consists of a frame with forks, headlamp and front mudguard attached; a repainted tank (missing some instruments); an engine; and sundry other spares (unrestored). The 1954 continuation logbook for the lapsed registration 'OC 7686' may assist the successful purchaser in applying to retrieve that number and re-register the motorcycle.
