Description
As a matter of course, Polini developed their own PVL internal rotor ignition: Ignition digital Polini Evolution PVL Minarelli horizontal (Yamaha Aerox / Nitro). The racing ignition comes with pre-programmed Polini ignition curves, but offers more options for adjusting ignition timing. Advancing, or delaying, ignition timing can considerably improve performance, so any serious tuner should consider getting a high-end digital ignition like this. The ignition was developed for 50cc to 100cc scooters.
The ignition comes with base plate, rotor, trigger plate, coil / CDI, spark plug cap, cables and small parts.
Attention: this ignition does not supply power for the lighting system.

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.
