Company information
Our company was founded in 1947 as a specialized manufacturer of motorcycle mufflers, which are key components of motorcycles. Since then, over the course of more than half a century, we have consistently engaged in innovative muffler production and have significantly contributed to the development of the motorcycle scene in our country. Currently, we are expanding our horizons by utilizing the unique technologies we have cultivated in muffler development and manufacturing, as well as processing technologies for titanium and magnesium alloys, to challenge ourselves in areas such as bicycle frames and welfare equipment (wheelchairs and handbikes). Our technology at SIW will continue to accelerate towards the realization of a rich society filled with dreams and hopes where people and nature coexist.
