Description
Internal Rotor Ignition Polini PP18 by PVL Vespa Primavera 125cc ET3.
Polini internal rotor ignition for 50cc Vespas with manual transmission. The ignition was developed in collaboration with ignition specialist PVL and will make the engine rev up much faster. Due to the reduced and well-balanced flywheel, the engine will become much more responsive. Even at high engine speeds, the ignition works much better than conventional ignitions and allows for higher peak power. As a matter of course, ignition timing can be set precisely. In addition, the CDI has a variable ignition curve that optimizes ignition timing in the upper rpm range. Definitely a purebred racing product, which also means that there is no power supply for the light system.
The ignition comes complete with base plate, rotor, fan wheel, coil with CDI, spark plug cap, cables and small parts.
- Developed in collaboration with ignition specialist PVL
- CNC machined base plate
- CNC machined flywheel (207g)
- Rotor with 20mm cone (323g)
- Plastic fan wheel
- Plug & play
- Without lighting
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.
