Collection: Twin Air

In 1972, the motocross world was given a historic boost by a revolutionary product: a laminated, dual-foam air filter that, when soaked in a special oil, allowed free airflow into the carburettor while keeping dirt, grime, sand and water out of it. It was effective, durable, washable and reusable. It took off, and the little start-up company that invented it, called Twin Air, hasn’t stopped ever since.
