Malossi 70cc Sport Cylinder Kit for Piaggio 50cc 2T Models (Suits Euro 4 Models)
This kit is particularly useful for the Aprilia SRMT 50 Euro 4, and the Piaggio Typhoon 50 Euro 4.
The Euro 4 models have a special fitting on the factory head to suit a temperature sensor which feeds information back to the ECU. The ECU on the Euro 4 models has the ability to advance and retard the ignition timing of the engine, it does so based on the RPM and the temperature reading at the head via the sensor. As the engine gets hot, the ECU backs off the ignition advance to allow the engine to cool.
Removal of the sensor results in the ECU maxxing out the advance on the ignition timing constantly, and can cause overheating and piston seizure.
This cylinder kit allows you to keep the factory head and temp sensor with the 70cc cylinder, problem solved! This kit can also be used on Euro 2 models if you’re looking for a cheaper option.
