Variable Racing Ignition MVT Digital Direct Simson

Variable racing ignition for Puch Maxi MVT Digital Direct

Digital ignition with variable advance across the entire rev range. This means that the digital CDI unit will adapt the spark advance from low to high revs, optimising your engine's performance throughout the entire rev band.

You will achieve a faster increase in RPM and greater power from a standstill.

It is recommended to switch all bulbs to LED or low-consumption conventional ones, in order to have both front and rear lights, and at the same time use external batteries for gauges, since the rotor does not charge the battery quickly enough.
