The Ariel Square Four is one of the most ingenious engines ever to power a motorcycle, with literally four vertical cylinders in little more than the space for two. Larry Horn of Huntington Beach, California shows us his 1957 Ariel Square Four MKII, which he restored himself.

In 1953, the ‘four pipe’ 997 cc Ariel Square Four Mk II was released, with separate barrels, a re-designed cylinder head with four separate exhaust pipes from two cast-aluminium manifolds and a rocker-box combined with the inlet manifold.
