Description
Stage6 Unrestricted CDI Piaggio Typhoon and SR Motard Euro 4
Stage6 open CDI ignition box for Piaggio Typhoon, NRG Power DD, and Aprilia SR Motard Euro 4. It removes the factory rpm restriction found on many stock models. This is an ideal solution for tuning a 50cc scooter with setups like a performance exhaust or a tuning cylinder. The CDI can also be used as a replacement for a missing or damaged stock part.
What are the benefits of a derestricted CDI?
On many 50cc scooters, the stock CDI unit limits engine speed to around 7,500 rpm. As a result, the engine cannot fully utilize its potential with a higher-performance setup. Replacing the stock CDI with the unrestricted CDI from Stage6 eliminates the rev limit to match a setup with performance parts. The final result also depends on the other components, especially the cylinder, exhaust, carburetor, and carburetor jetting.
This CDI module is suitable for applications such as:
- Derestricting a 50cc scooter with a stock engine
- Setups with a sport or racing exhaust
- Setups with a sport or racing cylinder
Connecting the Stage6 CDI
Installing the Stage6 derestricted CDI ignition box is easy thanks to its plug & play design:
- Disconnect the stock 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.

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.
