Ignition -POLINI IDM- Vespa PX, Cosa -w/o e-start models only
Part no.:
P1710549
Description
Polini offers with its IDM ignition an interesting alternative to the original ignition system.
The basic idea is also here a significant improvement in acceleration through significantly less flywheel mass. The pole wheel of the Polini IDM ignition weighs only 1,4Kg, so it is over 50% less than a standard PX fan wheel.
The resulting throttle response is fantastic and the acceleration is much more aggressive in the lower gears. The resulting throttle response is fantastic and the acceleration in the lower gears is much more aggressive. This is achieved by a lightweight construction where the rotor and fan are separate components.
Rotor weight: 1400 grams
Also suitable for PX models from year of manufacture. 2011

The ignition itself is based on a base plate of a 50cc automatic microller and has a frequency dependent ignition timing control. This is dynamically designed and adjusts over the speed band in a fixed pre-programmed ignition curve.
The engine adjusts the ignition timing dynamically (i.e. with change of the speed) by 8° crank angle. In the example (of the installation instructions available in the download area) you can see that a statically adjusted ZZP is adjusted from 23° from 1300 rpm to 15° at 8000 rpm.
If the ZZP is statically adjusted to 26°, you will land at 18° at 8000 rpm.
The dynamic adjustment helps the engine to achieve good torque and clean combustion even in the lower speed range, where a possibly existing resonance exhaust does not yet provide good support. In order to relieve the engine thermally, the ignition timing in the upper speed range is reduced again, since it usually has a good filling here.
Even in the lower speed range strong systems such as SIP Road or BGM BigBox profit from such an ignition. Here, in contrast to a real resonance system, the pre-ignition can usually be significantly increased again and the available torque can be increased well.
The ignition is a perfect replacement for the existing one and enables a much more agile engine performance. On models from 2011 onwards it is a prerequisite for further tuning as it eliminates the speed limit of the original ignition.
The ignition is connected to the original wiring harness and operated with the original regulator. This is only valid for models from 1984 onwards. Models with ignition lock on the handlebar cover still need a new regulator (ideal is BGM6690).
Note: Requires a pole wheel puller M22x1,5mm (see accessories).
