NARAKU NK390.16 CDI Unit — designed for urban 4T scooters, this racing-style ignition unit is aimed at riders looking to unleash the engine range and regain responsiveness. Compact and sold individually, it replaces the original module to modify the rev limit parameters and optimise ignition management.
Ideal for those who have fitted a big bore kit or who seek a more responsive engine in the city, this unit can provide a few additional kilometres per hour on certain machines. It is particularly suitable for 50 cc 4T scooters, such as the KYMCO Agility 50 I 4T Carry, the SYM Symphony 50 S, and the HYOSUNG NewTee Up 50 (check compatibility before installation).
Warning: on some inductive tachometers (e.g. Yager 50GT), interference may occur. Using interference-resistant connectors can mitigate these issues, but tachometer display anomalies may persist. Installation and adjustments are recommended to be carried out by a professional to ensure safety and compliance of the installation.
