The 50 ET2 ha sthe most sophisticated two-stroke engine ever mass-made produced.

The ET2 carries the Piaggio Hi-PER2 engine, also in line with Euro 2 standards as a result of its two-way catalytic converter and Secondary Air System, which feeds fresh air into the exhaust port, igniting unburnt emissions and cleaning up the exhaust pollutants. Fuel-air mixture sucked into the combustion chamber rushes out the transfer ports and helps to drive the previous cycle's burnt gases from the cylinder. Although most of the fresh mixture remains inside, a small percentage sneaks out to the atmosphere through the wide-open exhaust port.Without any physical barrier between the fresh mixture and burnt gases this is unavoidable.
