Introduced in 1958, the AJS Model 31 (and its Matchless twin, the G12) was developed specifically for the US.
This is the CSR variant, which stood for Competition Sport Road. Apparently competitors and critics called it the “Coffee Shop Racer”. The 646cc air cooled twin was good for 35 horsepower, and the bike weighed 396 pounds dry. Eventually the bike won the famous Thruxton 500 endurance race (for production based road bike) and the bike was given the nickname of Hurricane. By ’66, the company was going out of business and the Model 31 was done.
This example (VIN: 80692) has compression but no spark. It was last titled in 1990 outside of the US. I don’t like featuring bikes that need to be completely restored, but I never see Hurricanes come up for sale. Someone save this! Find it in Spokane, Washington with bidding up to $1,375
