SEM started its activity in 1961 working mainly in the motorcycle industry.
Since the mid-70's, our passion for motorcycles brought us to a close collaboration with race departments (Cagiva-Husqvarna) as regards construction and experimental analysis of exhaust silencers for racing motorbikes (motocross and speed).
Our silencers or mufflers have won several motocross championships through Cagiva and Husqvarna. This research has led us to experiment with new solutions, resulting in the production of technologically innovative, lightweight, and reliable silencers.
We have transferred the experience gained to the production of series, extending our range to road models and adopting new manufacturing materials like aluminium alloys, composites, and stainless steel.
Our advanced and fully robotised welding processes contribute to productivity and the precision of aesthetic finishes, allowing us to provide our customers with a product of the highest quality.
Corporate developments have strengthened the Prototype department, directing production to stamps, frames, and tanks. In addition, to meet the demands of our customers, we're moving towards the creation of small, customised series of stamped and assembled components.
