Stage6 Unrestricted CDI for Kymco Euro 4
Stage6 open CDI ignition box for Kymco Agility, Filly, Like, People, and Super 8 Euro 4 models. It removes the rev limiter that comes standard on many factory models. The ideal solution for tuning a 50cc scooter with, for example, a racing exhaust or a sport cylinder. The CDI can also be used as a replacement for a missing or damaged original part.
What are the benefits of an unrestricted CDI?
On many 50cc scooters, the stock CDI module limits the engine speed to approximately 7,500 rpm. As a result, the engine cannot fully realize its potential with a more powerful setup. Replacing the original CDI with Stage6’s open CDI removes the RPM limit and adapts the system to a setup featuring racing parts. However, the result also depends on the other components installed, particularly the cylinder, exhaust, carburetor, and carburetor jetting.
This CDI module is suitable for applications such as:
- Derestricting a 50cc scooter with stock engine
- Setups with sport or racing exhausts
- Setups with sport or racing cylinders
Connecting the Stage6 CDI
Installing the unrestricted Stage6 CDI ignition box is easy thanks to the Plug & Play system:
- Disconnect the original CDI
- Plug in the Stage6 CDI ignition box
- Check for proper operation before riding
Checking the carburetor jetting after installation is recommended. Depending on engine speed and the exhaust setup, adjusting the main jet and carburetor settings may be required.

ATTENTION: Please check before ordering to ensure that the ignition module matches the model originally installed on your vehicle.
CDI and coil
The CDI (for Capacitor Discharger Ignition) and the ignition coil are an essential part of the ignition. While the coil is actually just an energy storage device that supplies the ignition spark to the spark plug, the CDI module is a more complex component that controls the engine speed at which the spark should occur. It can therefore have an effect on engine behavior and performance.
Open CDI
Many riders equip their 50cc geared mopeds and scooters with open, i.e. derestricted CDIs. In most cases, the original CDI throttles the maximum achievable engine speed, which significantly reduces performance and top speed.
To remove this rev limiter and thus increase maximum speed, you can install a CDI without a rev limiter instead of the original CDI.
Beware! When using an open CDI, the carburetor must be readjusted, so it is best to order new jets as well.
Programmable CDI
Programmable CDI control units are available for tuned racing engines on 50cc scooters and moorcycles as well as for motocross bikes. These CDIs are designed for more experienced tuners who want to optimize the settings of their two-wheeler as much as possible.
With a programmable CDI, the ignition timing is dynamic so that the spark always jumps at the optimum time at both high and low engine speeds. This leads to a better increase in speed, higher torque and an overall increase in maximum power.
4-stroke engines with fuel injection are equipped with an ECU (Electronic Control Unit), which also controls the fuel injection. When tuning a four-stroke engine with an electronic injection system, a programmable CDI is therefore an absolute must in order to avoid breakdowns and engine damage.
Symptoms of a defective coil or CDI
If these two elements fail, the symptoms are usually very easy to recognize: no spark at the spark plug, so the engine will not start.
It is best to proceed in sequence: First change the spark plug, then the spark plug cap, then the coil and only then consider the CDI or the ignition itself as the source.
