CDI unit unrestricted Stage6 Peugeot Speedfight 4 50 4T euro 4

Stage6 unrestricted CDI unit for Peugeot Speedfight 4 50cc 4-Stroke Euro 4 with carburetor, compatible with models manufactured between 2018 and 2020.

On some 50cc scooters, the standard CDI unit may limit engine speed to around 7,500 rpm. With a completely original setup, this may go unnoticed, but when fitting a Sport exhaust, Sport cylinder, or other performance parts, this limitation can prevent the engine from making proper use of the rest of the setup.

The Stage6 unrestricted CDI unit removes this restriction, allowing the engine to operate across a wider RPM range and make better use of the rest of the setup. The final result will always depend on the scooter's cylinder, exhaust, carburetion, and tuning.

It can also be used to replace a damaged or missing original control unit, provided that the scooter matches the compatible version.

What will you achieve?

• Remove the rev limit of the original CDI unit.
• Allow the engine to continue gaining RPM when the setup requires it.
• Make better use of a Sport / Racing exhaust.
• Combine it with a sport or higher-performance cylinder.
• Prevent the original control unit from being the component that limits the rest of the setup.

Plug & Play installation

Installation is simple: you only need to disconnect the original CDI unit and connect the Stage6 in its place. This model has 18 connectors and is designed to directly replace the original control unit on compatible Speedfight 4 versions.
