Description ECU / CDI Unrestricted for SYM Crox 50cc 4T ECU/CDI from Naraku without restriction / SYM Fiddle / Crox 50 Euro5 Install this CDI to release the full engine power, which can be very important especially when using tuning parts (cylinders, exhaust, etc.). The speed limitation of the original CDI is canceled. To fully unthrottle the scooter, it may be necessary to remove other throttles (e.g. on the variomatic). Beware! When using an open CDI, the carburetor must be readjusted, so it is best to order new jets as well. Simply install instead of the original CDI. For 50ccm SYM with Euro 5 4-stroke engine. Note: Does not fit models with Continental CDI with imprint XUA-E5V, please check before ordering. * Performance scooter parts do not come with a warranty*
