Engine

The Speedfight 1 and 2 were equipped with either an air-cooled or liquid-cooled 50cc 2-stroke engine with a vertical cylinder or a 100cc air-cooled 2 stroke engine with a vertical cylinder. Both 50cc air- and liquid-cooled engines shared the same bottom end, where as the 100cc engine has a tougher connecting rod, crankshaft, among other things.
The Speedfight 3 and 4 featured a horizontal cylinder 50cc 2 stroke engine, equipped with an electronic oil injection pump made by Dell'Orto, among various other design improvements. This engine was also shared in various other Peugeot scooters, like the Peugeot Ludix, Jet Force, New Vivacity, Streetzone, etc. The Speedfight 3 and 4 also came with a 50cc 4 stroke engine, a derivative of the popular GY6 4 stroke scooter engine. In the Speedfight 3 and 4, it seems to match the 4 stroke 50cc engines made by SYM, due to various engine parts being compatible with the ones found on SYM's engines.
