Internal Rotor Ignition MVT Digital Direct with light Derbi Euro 2 / Euro 3

MVT Digital Direct

The MVT Digital Direct ignition is the brand's top model, with extreme performance, agile engine and optimum response at all engine speeds thanks to a lightweight internal rotor and CDI with variable ignition timing. Bonus: the ignition has a 12V output for lights / on-board electronics!

The DD internal rotor ignition has a digital CDI with variable ignition timing adjustment, i.e. the ignition timing adapts to the engine speed and is therefore ideally suited for tuned engines. In this way, you always get the best ratio between torque and maximum power, regardless of RPM.

Advantages of MVT Digital Direct

• Digital internal rotor ignition
• With light
• Simple adjustment
• CDI with variable ignition timing = maximum power at all RPMs

 Inner Rotor Ignition

An internal rotor ignition is a racing ignition designed to increase performance. Inner rotor ignitions are designed for motorsports and competition, in rare cases they also provide power for vehicle lighting. (e.g. the MVT ignition).

Advantages of an internal rotor ignition

Inner rotor ignitions are the ultimate choice for the race track, they are however  not really suitable for street use.
The compact and lightweight internal rotor puts less weight on the crankshaft and allows for quick revving, very high engine speeds and an enormous power increase at high rpm.

Another advantage is that this type of ignition is less susceptible to moisture than standard ignitions.

Tip: You may want to consider a tuning ignition cover with additional holes / cutouts to improve ventilation.

Disadvantages of an internal rotor ignition

RPMs increase faster due to the lower mass, this will affect torque at low RPMs, though. Therefore, internal rotor ignitions are only worthwhile for racing, because on the racetrack you'll constantly stay at high engine speeds.

Installing and adjusting an internal rotor ignition

Installing an internal rotor ignition requires technical knowledge and careful adjustments to keep the engine running optimally and really optimize performance. We recommend our tutorial to learn how to install and adjust an internal rotor ignition.
