Stage6 CDI with Remote Control for Restricting / Derestricting Rieju, Beta, Sherco (Moric)
Stage6 offers this CDI with remote control for many 50cc motorbike models, including brands like Rieju, Sherco, Yamaha, and many others. It allows easy restriction and derestriction of the engine speed via a remote control.
Stage6 CDI with remote control - how does it work?
This CDI allows activating and deactivating the rev limiter that comes factory-installed on several models. Switching modes is done conveniently using the included remote control.
This is an ideal solution for tuning a 50cc bike with setups like a racing exhaust or a sport cylinder. The CDI can also be used as a replacement for a missing or damaged stock part, while simultaneously offering the ability to re-restrict the moped during a traffic stop or technical inspection.
Available modes:
- Mode A: RPM to 4,000 rpm
→ Anti-theft mode: The moped is barely rideable - Mode B: RPM limited to 7,000 rpm
→ Top speed of approx. 45 km/h - Mode C: RPM limited to 8,000 rpm
→ Top speed of approx. 50 km/h - Mode D: Maximum RPM of 16,000 rpm
→ Unrestricted
The CDI features a small display that shows the currently selected mode. It is also equipped with a pairing button to link the unit with the remote control(s).
Thanks to the plug & play design, installing the Stage6 derestricted CDI ignition box is very easy.
What are the benefits of an unrestricted CDI?
On many 50cc geared bikes, 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 Stage6 unrestricted CDI eliminates the rev limit to match a setup with racing parts. The final result also depends on the other installed components, especially the cylinder, exhaust, carburetor, and carburetor jetting.
This CDI module is suitable for applications such as:
- Derestricting a 50cc motorcycles with a stock engine
- Installing a sport or racing exhaust
- Installing a sport or racing cylinder

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.
