Another of Edward Turner’s innovative designs the Square Four was shown as early as 1930 at the Olympia Motorcycle Show. Originally an overhead-camshaft 500cc, it developed into a 600 before a total redesign saw it become the 1000 cc 4G. Post War telescopic front forks became available as was the plunger rear suspension frame and the cast-iron cylinder head and barrel was replaced by alloy components in 1949.
Square Four production ceased in 1959 with all of the other Ariel four-strokes models in favour of their light weight two stroke ‘commuter’ bikes, a tragedy for a superb and now much loved and revired motorcycle capable of achieving 100 mph.
Declared manufactured 1955 this MKII Square Four had a gearbox rebuild in 2012 by the previous owner, parts supplied by Dragonfly Motorcycles ( Invoices on file ). In excellent running order the bikes overall cosmetic condition is also very good, finished in black the body work paint is good no dents or scratches in the tank, the frame and forks are also in fine condition with no signs of corrosion.
All the bright work / chrome is also in generally good. Having been laid up for a while the bike has had a recent check over and is ready for the road, supplied with the current UK V5C logbook. A great ridding classic and a sure fire investment for the future as they are certain to gain much value.
