This open racing CDI increases the final speed depending on the model by approx. 5-15 km/h and should be your first choice for tuning measures. The Racing CDI adjusts the ignition timing depending on the speed. Compared to the open/sport CDI, acceleration, start and final speed are also slightly improved.
The CDI is the most important throttle on the scooter, with which speed and final speed are consistently reduced.
Installation: pull old CDI out of the plug, plug in the new one, done!
Important: This CDI only works on models with 4-stroke engine. Please compare plugs with picture, as some models have different CDIs installed. Plugs must be identical. (Double plug 4+2 pins).
Further details and screwdriver tips see below in the item description.
