1930 Triumph Model CTT 500cc OHV Solo


1930 Triumph Model CTT 500cc OHV Solo

The new 498cc Triumph was introduced at the Olympia Show in 1929 and created much interest among the buying public for this popular motorcycle. Closely following the lines of the existing 350cc model CO, the model CTT was road tested by MotorCycling in March 1930 and fully satisfied the tester in ass respects as a worthy product of a firm with a household name. The motorcycle was particularly noticed for the design of handlebars, the first to adopt the layout suggested by the Standardization Committee of the Manufacturers Union. Twistgrip controls were provided for both throttle and magneto advance.
