1957 Arial Square Four MK2
Specifications
Description
The Square Four engine was originally designed in 1928 by Edward Turner.
The 1000cc four-cylinder was a slow revving, torquey engine that was meant for cruising over long distances and low rpm or tugging a sidecar. They weren’t high-revving, high performance machines. But in their day, they had a reputation for reliability.
The one-piece iron cylinder block had all four cylinders arranged in a square pattern (hence the name) with a one-piece removable cylinder head. It was all fed by a single SU MC2 carburetor, and each bank of cylinders (left and right) shared a common exhaust manifold exiting with one pipe per side. This arrangement doesn’t make for great airflow, but again, this wasn’t a racer, this was a cruiser.
The Square Four went through a major revision in 1953, with a new cylinder head and manifolds, prompting a new sub-model designation, Mark II, which ran from 1953 through Ariel’s final year, 1959. Prior to 1953, both cylinders on each side shared just one exhaust pipe, hence the nickname “2-pipes”. But new intake and exhaust manifolds and the new head gave each cylinder it’s own exhaust pipe, hence the term “4-pipe” bikes. This 57 Square Four of course benefited from these improvements, which yielded a bump in power to 40 horsepower, allowing a top speed of 100 mph.

Of course, the Ariel Square Four was never intended to be a road rocket. With two counter-rotating crankshafts, it was meant to be very smooth.
These bikes are cruisers, designed to pull a side car or cruise at speed all day long. In fact, its fair to note that there weren’t many bikes in the 1950's that you could say that about.

Waimak Classic Cars does not know, and cannot give advice on how good any restoration work on the vehicle had been.
The Purchaser acknowledges that the vehicle is being sold as a classic car; that in terms of the Act and the nature of the goods, the vehicle is an old car, bike or boat, that may have visual and hidden faults, unlike a new motor vehicle.

While the Purchaser is entitled to rely on statements given by Waimak Classic Cars as being correct, where goods such as vehicles are concerned, with so many moving parts and rust being an issue with older vehicles; a Purchaser who chooses not to seek independent professional assistance when assessing the quality of what they propose to buy is considered as buying at their own risk, and if the vehicle then turns out to be of less than the represented quality, or not up to the Purchaser's expectation, or in the Purchaser opinion not fit for purpose; then the Purchaser is considered to have contributed to their own loss and should not expect any refunds or betterment from Waimak Classic Cars.
The Purchaser acknowledges that they have read and fully understand this notification and the nature of a car which is many years old.
