This cylinder will come out 5.3cv with its original cylinder head. Its stroke is 43mm with a compression ratio of 1: 10.7. Clearly, a high engine ideal for a quality refurbishment.
Unlike the DR PERFORMANCE kit, this one has an exhaust outlet oriented downwards , which makes it the ONLY cylinder with this type of configuration for your AUTOMATIC 2T scooters
Equipped with a two-segment piston , this cylinder provides unrivaled torque and you can expect a good 70km / h with a carburetor setting and a good irridium spark plug.
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder.
