Period: Unknown
Canada: Ariel Motorcycles was a British motorcycle manufacturer based in Bournbrook, Birmingham. It was one of the leading innovators in British motorcycling, and was part of the Ariel marque. The company was sold to BSA in 1944 but the Ariel name survived until 1970. Influential Ariel designers included Edward Turner and Val Page.
Function: A tube that, when filled with pressurized air and put inside the casing of a pneumatic tire, helps support the vehicle to which it is attached, as well as helping to absorb shock when the vehicle is in motion.
Technical: The Square Four is a motorcycle produced by Ariel between 1931 and 1959, designed by Edward Turner, who devised the Square Four engine in 1928. At this time he was looking for work, showing drawings of his engine design to motorcycle manufacturers. The engine was essentially a pair of 'across frame' OHC parallel twins joined by their geared central flywheels, with a four-cylinder block (or Monobloc) and single head. The idea for the engine was rejected by BSA, but adopted by Ariel. Thus it became the Ariel Square Four. In 1949, the Ariel Square Four Mark I saw the cast-iron cylinder head and barrel replaced by alloy head and barrel. This saved about 30 pounds (14 kg) in weight. The 1949 machine weighed around 435 lb (197 kg) dry, produced 35 bhp (26 kW) at 5,500 rpm. The Mark I was capable of 90 mph-plus.
