In gasoline engines, the secondary air valve is activated during a cold start in order to minimize the exhaust gas components HC and CO in the warm-up phase. Oxygen-rich ambient air flows past the combustion chamber and directly into the exhaust ducts. There, the unburned exhaust gas components are "afterburned", which reduces pollutant emissions and also brings the catalytic converter up to operating temperature more quickly.

This system was developed primarily with a view to the EURO emissions standards. When converting a bike to race track use (without catalytic converter, etc.), we recommend removing the side air system (SAS).
