Who we are.

It was in 1953 that Kushitani began making a one-piece leather suit. The client was Suzuki at that time, there were no leather suits in the country, and it was said that the production was imitated by looking at foreign catalogs. At first, the leather jacket and the leather pants for riding were simply connected to form one piece. It was characterized by being thin and supple with veal leather. It was an era when there was no fully paved circuit in Japan, and the paved road race was held at the US military airfields such as Kyushu and Konosu, and the road race itself did not exist. The one-piece leather suit completed after trial and error showed its true value in the Asama Kogen race in November 1955 (the 1st All Japan Endurance Road Race). The client, Toshikazu Ito, Toshio Kamiya and Hayashi Yamashita, wore it highly. After this, starting with Honda, Japanese manufacturers will start participating in the Isle of Man TT and the World GP. Of course, Kushitani's leather suits have become smarter to fit the body since the Asama era. In 1962, Kushitani leather suit debuted in the Isle of Man TT race. It was worn by Suzuki's Ernst Degner (GP50 winner) and Mitsuo Ito (5th in the class). The following year, 1963 Mitsuo Ito won the first Japanese Isle of Man TT (GP50). I also wore Kushitani. In September 1962, the first fully paved racing course in Japan, Suzuka Circuit, was completed. In 1963, the World GP was held, and the Japanese road race finally dawned.




Hard knee cups appear Protection has evolved
 gardner.jpgIn the 1970s, the number of GP riders wearing a colorful leather suit gradually increased from the previous black one. Iniwasakimasaru.jpg addition, the manufacturer name and rider name will be put in the leather suit. Although some riders still prefer calf leather, adult cow leather, which has better tear strength and resistance to friction, has become mainstream and has increased in thickness. The biggest change was protection. The machine is faster, the tire grip is higher and the bank angle is deeper. If you fall at that deep bank angle, you immediately hit your knees on the road. Therefore, a hard protector made of resin was built in the knee. And when Yano Saarinen showed a hang-off riding style with the hips inwardly shifted, and American riders from dirt tracks started kneeling down on the road, the leather suits changed. However, there are no knee sliders and the leather will be torn as it is, so we covered it with thick adhesive tape or sewed leather from above for reinforcement. Some riders were wearing hard leather for the soles of leather shoes. The silhouette also changes. The paper pattern has been devised to fit the body, making it easier to tilt forward. A large pad with urethane sponge sewn from the waist to the back also appeared. The leather suits evolved greatly with the speed of the race.
