This coil is used with Pietcard CDI boxes, and are geared at Garelli mopeds with CEV, Bosch, Ducati Stator plate and flywheels. Will fit other bikes as well. Experiment!
Basically, take this coil, and a CDI box, and then you can replace your points and condensor while reusing your original everything else. Check out the installation diagram for more info. Easier then setting your points!
