O.K Supreme 1930 500 cc OHV JAP frame#14858 engine# KOY/ W 5250 S
OK motorcycles were manufactured from 1899 till 1939: from 1926, when one of the controlling partners left the firm, the company was renamed OK Supreme.
The company had some success in racing in the twenties and was sufficiently well established to overcome the downturn in trade in the Depression years.
From the late twenties the company used SV and OHV JAP engines only.
This machine, weighing 300lbs and capable of ca. 75 mph, is equipped with a double port sporty OHV engine and is an older restoration.
