Does a CDI box for Yamaha raptor 50 change the speed?

A CDI (Capacitor Discharge Ignition) box can affect the performance of a Yamaha Raptor 50 by altering the ignition timing and rev limit, which may lead to improved acceleration and responsiveness. However, it does not directly increase the top speed, as that is primarily determined by the engine's design and gearing. If paired with other modifications, a CDI box might contribute to better overall performance, but it's not a standalone solution for increasing speed.
