1966 Velocette Thruxton
1966 VELOCETTE THRUXTON
Velocette has a proven design in their 500cc Velocette Venom. Big singles had sort passed from grace in the 1960s with the advent of all the twins pouring out of Britain, and now the high-revving, and totally-reliable twins coming out of Japan. Velocette didn’t have the funds to design a totally new bike with a modern engine. Finances forced them to do with what they had. Fortunately, the Venom had proven to be fast, reliable, and robust. Velocette designer Bertie Goodman put together a “racing kit” that included an extensively-modified cylinder head with bigger valves and a downdraft intake port, an Amal GP carburetor and special cam followers, in 1965. The new carb was so big that they had to hollow out the underside of the fuel tank to make room for it. The following year they named the new bike the 1966 Velocette Thruxton, also known as the Venom Thruxton. The new Thruxton was a bona fide race bike capable of 120 mph with handling to match.
