Engine control unit / ECU / CDI from NARAKU, open / unrestricted with matching intake hose for 50cc 4-stroke Yamaha Aerox built from 2018 and up with Euro4 emission standard.

The CDI has no speed limit, so the engine can be completely de-restricted and the entire speed band can be used (in some circumstances it may be necessary to remove other throttles, for example, on the variator): Path clear for tuning cylinder and racing exhaust.

This NARAKU ignition box can be replaced plug-and-play immediately ready for use against the original CDI and of course also used as a spare part.
