Suzuki GT Series - GT250

GT250

For the 1973 MY, the venerable T250 twin was updated with new bodywork, gained Ram Air cooling, a single disc brake in front and was now designated GT250. This model thus filled the important 250cc displacement slot in Suzuki's GT lineup. The GT250 retained its original engine and six-speed transmission, both remaining basically unchanged from the T20 X6 Hustler of 1966 through the T250 model to the 1972 MY. The marketing name of "Hustler" was retained for the North American market. The GT250 continued on with minor changes until the 1976 MY when the engine was changed substantially, both internally and externally. Porting changes now saw the cylinders with four larger transfer ports instead of the previous two smallish ones as well as changes to the CCI system in the crankshaft main bearing area. The carburetors became 28 mm in size instead of 26 mm, the mufflers were modified to cater for the increased airflow through the engine and the transmission ratios were revised to more evenly match the new powerband. The Ram Air cover for the head was deleted and the stock finning on the heads was increased in height to gain the same effect as the Ram Air used to give.
