CDI ignition unit Polini for Piaggio, Gilera 171.0514 fitting for Piaggio Sfera 50 NSL1T 1991, 3,7 PS, 2,7 kw

Polini CDI ignition unit with variable ignition timing. Depending on the engine speed, this ignition unit adjusts the ignition timing optimally and thus enables the engine to be revved up cleanly as well as optimum torque at all times. With the supplied toggle switch a speed limiter is activated and the CDI throttles down the engine. Only useful for tuned vehicles with corresponding cylinder kit and exhaust system.
