1959
Ariel
Square Four MKII
The Ariel Square Four was a British built motorcycle between 1931 and 1959
The MKII Ariel had a redesigned frame to provide clearance for the high mounted SU carburetor
This marvel of ingenuity produced 40 hp and was capable of 100 mph top speeds
This example has been painstakingly restored by the experts at Retrospeed in Belgium, WI
The 997cc 4 stroke engine has a very unique design using two mated transverse crankshafts
The Plunger style rear suspension was used from 1939 until the end of its production in 1959
This actual 1959 Ariel Square Four is believed to be one of the last imported into the United States
Motorcycle Classics magazine ran a front cover feature on this bike
