1965 - 1970 Velocette VENOM THRUXTON[edit | edit source]
The following year this went into production as the Velocette Thruxton. Also known as the Venom Thruxton, this aimed to fill the gap left by the demise of the BSA Gold Star and was named after the Thruxton Circuit race track on a former wartime airfield in Hampshire. The Velocette Thruxton was a true racer, with a full race specification cylinder head that was gas flowed by hand to accommodate extra-large valves and a downdraught inlet port. The Amal carburetor was so large it required a distinctive cutaway in the bottom of the fuel tank, and race cams boosted performance to up to 120 mph (190 km/h).
