Music to many motorcyclists’ ears is the approach of an Ariel Square Four. That unstressed ‘thwump thwump’ from the Edward Turner designed, 601cc single block of four cylinders, with twin geared together crankshafts pushing pistons at 180 degrees and serviced by vertical valves, well it is going to be a bit special, isn’t it? A Gentleman’s bike they called it, possibly because it politely circuited the Isle of Man TT track rather than joining in with the more competitive entries. A luxury tourer then, which will appeal to those who seek to maintain and use a true classic motorcycle without inflicting distress to arthritic ligaments and damaged vertebrae.

We understand that this striking Square Four was the subject of a complete and costly restoration in 2014 – 15. As well as the obvious cosmetic attention, work also included an engine rebuild, with new liners and pistons fitted, and the magneto and dynamo were also restored at that point. All bolts and many of the fittings were replaced with stainless steel, and the motorcycle was repainted to concours standard. We are informed that the brightwork is immaculate, apart from slight pitting to the left exhaust and to the front wheel. In 2016, the Ariel sold at auction for £25760 and the current enthusiast custodian purchased the motorcycle in 2018, and has continued to maintain it to a high standard. It really is a delightful example, with an appealing registration number, and the vendor assures us that it is probably the nearest one could get to purchasing a brand new Ariel Square Four.

The history file contains the V5C registration certificate, an RF60 continuation book (detailing the motorcycle’s keepers during the 1950s, who resided in the Bristol area), photocopies of parts books, a workshop manual and many invoices detailing parts procured for and time spent on the aforementioned restoration.
