ITALKIT offers you this analog internal-rotor ignition for your GAS GAS 125cc. In partnership with SELETTRA, ITALKIT offers you a competition internal-rotor ignition with no lighting, so you can rev your engine faster and push your breaker back to 18,000 rpm. This model is called analog because the spark is fixed. It is not a variable advance. This complete package comes with its plate, rotor, stator, coil and grounding braid. There's no reason to expect a gain of more than 2 hp from this ignition. We really appreciate the quality of this product and its finish.
