The '''Suzuki GT250''' is a [[motorcycle]] produced by [[Suzuki]] from 1973 to 1977. | The '''Suzuki GT250''' is a [[motorcycle]] produced by [[Suzuki]] from 1973 to 1977. Suzuki GT250 was an upgraded version of the [[Suzuki T250|T250]]. In fact, the very first models (released in Japan) were exactly the same bike, only the model name was different. When the model was presented in the rest of the world, the additional ”G” in front of the T250 model name was to show that the model has been modernized with a disc brake at the front and with a new Ram Air cylinder head. | ||
If we take a closer look at [[Suzuki]]'s 250 models before the T250, we will find out that the [[Suzuki T20|T20 Super Six (X6 Hustler in the USA)]] had very much in common with both the T250 and GT250. Many parts from the sixties' T20 (and even the T10 from the early sixties) will fit to them. | |||
When the GT250 model came (1971 in Japan, 1973 in Europe), it was still, despite of its roots from the sixties, a very competitive machine. It was as large as many 400 models and even performed like one, or better. In many countries, among them the Great Britain, it was the best selling motorcycle until the mid seventies. Unfortunately the environment rules that came along in the seventies made it harder to make any significant improvements to the [[two-stroke]]s and a development of four-stoke engines became the main concern of Suzuki's engineers. | |||
Already the 1965 T20 had a 30 hp two-stroke engine, automatic oiling, six speed gearbox, rev counter and a twin leading shoe brake at the front — very hot stuff for the era but not as revolutionary at the seventies. The T20 was ahead of its time, but the GT250, that used the same engine, was outclassed by a number of its contemporaries already in the late seventies. | |||
The T250 had a slightly more powerful engine than the GT250. The environmental and noise regulations of the early seventies forced Suzuki to redesign the exhausts, somewhat poorer performance as a result. | |||
Just a quick bit of info on the differences that between the Ram Air J-K-L-M (1973—1975) models and the later A-B-C (1976—1978) variants: Ram Air motors are quite closely related to earlier T250's and share the three main bearing crankshaft arrangement, and the carburetors are bolted directly to the barrels. A-B-C variants have a revised crankshaft using four main bearings and different lubrication arrangements, also the barrels are different in construction using different stud spacing, and rubber inlet stubs which mount the carburetors. | |||
