The Malossi Vespower ignition is based on the same principle as the well-known Vespatronic, Pinasco Flytech or Polini IDM. The ignition base plate does not have a pickup. The ignition signal is picked up via the light frequency. As the engine speed increases, the ignition timing is reduced via the CDI. The engine has a high pre-ignition angle for high torque in the lower speed range. This is reduced with increasing engine speed, at which the exhaust strongly supports the charge change.
The light flywheel mass ensures a very dynamic throttle response and greatly improved acceleration. The smaller fan blades are perfectly suited to the higher speed level of the tuned engine, at which the large blades of the original fan wheel would spin idle. The ignition is also suitable for everyday and touring engines thanks to the optionally available and adaptable flywheel rings. Here, the increased flywheel mass helps the engine to run smoother and improves elasticity in the upper gears. The stiffening fins of the plastic impeller effectively prevent tearing or breaking
