Suitable for Vespa Rally 200 with Femsatronic ignition up to chassis number VSE1T*0033996*.
The breaker cam is an important component of the Femsatronic ignition of the early Rally 200. It determines the geometry for triggering the ignition and must therefore fit properly and be technically flawless. As soon as the seat, groove or running surface are worn, the cam should be replaced.
The distance between cam and pickup should be 0.25 mm to 0.30 mm on the Vespa Rally 200 with Femsatronic ignition. This value is important for a clean and reproducible function of the ignition.
The original feather key (colloquially known as a half-moon key) for the Rally 200 Femsatronic is no longer available.

The breaker cam for the Rally 200 Femsatronic is a small but ignition-relevant component. If you ensure a tight fit, an intact groove and the correct distance to the pickup during the overhaul, you will create the basis for a cleanly functioning Femsatronic ignition.
