Founder Masaharu Okazaki founded the Okazaki Speed ​​Technology Research Institute. In the early 1970s, while tuning motorcycles and automobiles on the market, his lifework, high rpm, high output, gathered the best of his own theory and technology. Succeeded in developing the original engine TC16-MA1. However, because of its high output, the off-the-shelf clutch, transmission, and differential gear that transmits power to the final drive wheels make noise. In order to transmit the maximum output of the engine to the end, his extraordinary passion that "if it breaks, make something that won't break" and the belief that "you won't know until you try" continue to today's OS Giken. It has been inherited and transformed into products.
