When the BSA Group axed Ariel's entire four-stroke range in 1959, it brought an end to production of the unique 'Square Four', which had been around in various versions since late 1930. As the supply of spares dwindled, Redditch-based 'Squariel' enthusiasts the Healey brothers – George and Tim – began manufacturing parts, a venture that became a full-time business in 1967. The Healeys wanted to offer an updated Square Four as a complete motorcycle, and seeking suitable cycle parts turned to Roger Slater, who had obtained the UK manufacturing rights to Fritz Egli's spine-type frame. Metal Profiles supplied the front fork and the large drum brakes were sourced from Italy. Later versions had disc brakes and cast alloy wheels. The Healeys claimed that their new 1000/4 produced 50bhp, some ten horsepower more than the old Square Four, and weighed 80lbs less, all of which added up to a measurable improvement in performance. Hand built in small numbers, the Healey 1000/4 was expensive to make and demand for such a machine was necessarily limited. Production petered out towards the end of the 1970s.
Acquired by the vendor in December 2011, this rare Healey 1000/4 is the first production model to leave the factory. It is understood that the machine has never been restored and as such is the benchmark for all other Healey Square Fours. Since acquisition the machine has been kept on the road, with only routine service items changed as required; it will be freshly MoT'd prior to sale.
Modifications include a high-output alternator, Sparx rectifier, and Newtronic electronic ignition, while the oil cooler has been disconnected (it was over-cooling the engine). The rev counter does not work but a new one is included in the sale. Accompanying documentation consists of an Ariel OMCC dating certificate, old/current V5/V5C Registration Certificates, history sheet, and current MoT.
