Suzuki started racing in 1953 with its Diamond Free cyclemotor and has seen on the racing tracks and trails ever since. Early on Suzuki realized the importance of participating in races with winner machines. It gave the publicity needed to establish the name Suzuki and also gave important data needed in developing better machines for everyday use.

By 1954, Suzuki was producing 6,000 motorcycles per month, and changed its name to Suzuki Motor Co. Ltd in June 1954.

Suzuki's first mass produced car, the Suzulight, was a technical marvel. It included radical innovations for the time such as front-wheel drive, four-wheel suspension, and a rack-and-pinion steering.

A 250cc twin, Colleda TT - The Colleda TT is the predecessor of all Suzuki 250cc 2-stroke twins, including the T20, T250 and GT250. The air-cooled engine had a square 54 x 54 mm bore and stroke, the same as all of the models just mentioned. It also had new ”modern” floating swing arm with shock absorbers at the rear but the leading front fork design makes one to think of the early BMWs.
