CDI PIAGGIO for models with immobilizer

black, multi plug
Grade A – original restoration
Product description
Certain models of Vespa, such as the 50cc two-stroke models already possess an integrated CDI, contained within the ignition coil/electronic unit. The motors of the modern four stroke Vespa models fitted with carburettors from 125cc (and the 50cc four-valved, four strokers) possess separate ignition coil and CDI units. When the CDI unit fails it causes the motor to misfire. This can also lead to a complete failure of the whole electrical system and should be replaced immediately. If they are not otherwise labelled, the CDI units are compatible with all models that possess an electronic immobiliser device.-TIP : To help protect against harmful corrosion all electrical connections should be treated with WD-40 (#14253000) or similar. This is an original PIAGGIO spare part in first-class quality. PIAGGIO parts undergo a continous quality management process and are a symbol for long life products.
