Capacity: 247cc Power Output: 29 bhp/ 7.500rpm. Weight: 143 kg (316 lbs) Top Speed: 145 kph (90 mph)

When Suzuki introduced the X6 in 1965 it caused an immediate stir, especially among lovers of light-weight high-performance engines. The small 247cc air-cooled two-stroke engine was capable of almost 90mph and the motorcycle was suprisingly sophisticated.

The goal was to get 100 hp per one liter cylinder volyme, that is 25 hp from a 250 cc engine. Suzuki engineers acchieved this gole and even better. The 250 cc Super T21 (very similar to T20) that came 1966 had even more power: 30,5 hp.

Among the features of interest on this model was unusual separation of the oil pump instead of the typical oil/gasoline premix system. The Hustler was extremely popular and, at the hight of production, Suzuki produced over 5000 machines per month. Totally 35.500 T20/T21 was sold worldwide 1965-1967. Despite it's success, the X6 was only produced for three years.

A offroad version of the T20 was introduced (1967?) with the name TC250 (also called X6 Scrambler). See pictures of Supoer T21 and TC250 at the end of this page.
