Variable Racing Ignition MVT Digital Direct 29 Puch Maxi

Racing variable ignition for Simson 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 the performance of your engine throughout the entire rev band.

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

It is advised 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 / cells for gauges, since the rotor does not charge the battery quickly enough.
