1955 Ariel Square Four Combination
Reg. no. WBH 609
Frame no. GL685
Engine no. Unknown
The ‘Squariel’ was produced from 1931 to 1959 and has become one of the best-known British motorcycle designs from the period. At the centre of the design was an interesting engine – not in a straight or V configuration as with most multi-cylinder motorcycle engines, but rather in ‘square’ form. Also known as U configuration, this involved two pairs of cylinders in parallel, with each pair having its own crankshaft. The crankshafts were counter-rotating, the idea being that this would cancel out any vibration that might otherwise arise, making the engine as smooth as possible. Over time the engine evolved from 500cc to 1000cc, and by the 1950s the bike was producing 40bhp and could reach 100mph.
This 1955 Square Four comes with a Steib Sports sidecar. German company Steib has long been regarded as one of the premier sidecar manufacturers, their products having an excellent reputation for quality and style and are extremely collectable in their own right. The bike comes from a private collection and has seen little use recently so may require some recommissioning; it is offered with a V5c and an old-style logbook.
