1957 Ariel Square Four MKII
Frame no. GM919
Engine no. NML900
By 1957, when this Mk. II version of the 1000cc Ariel Square Four was produced, the design had just two more years to run. Here we see that the bike has thrown off most of its 1930s styling cues and is starting to look quite modern, with sportier, less valanced fenders, a scooped dual saddle and a jaunty little cowl for the headlight. Engine updates included a redesigned cylinder head with separate exhaust outlets, hence the bike's "four-piper" nickname. Good for 40hp, the motor would haul the Ariel up to an even 100mph; more importantly it had the grunt for relaxed sidecar duty.

Complete and unmolested, the Square Four was treated to a repaint while in the Lattin garage, otherwise it is as purchased.
