        My new rt125 was such a poor starter,that in the first year of ownership i had only completed 1000 miles.  I binned the extra air system. This improved the starting a little.

        Then I fitted the High Performance coil. Problem completely solved.

      Okay, I’ve read what you said.  It looks like you need new coils, if there is no spark coming from them.

      If the bike “cranks” from the start button, the CDI is working  (it means the regulator is also working)

      The last enemy before firing up would be your coils.     Regular hyosung coils do fail way more common than you realize 😉

      For plugs,   CR8E-iX  or ngk lasers work best & makes cold starts way better.

      Were the coils changed before on the bike ? if its under warranty the dealer should replace them.

        I have the coils at home anyway, can always send em out.

        High Performance Ignition Coil :: Hyosung GV GT 125 250 R + RT RX 125

        I’m sad to hear there isn’t much more hyo presense in Scotland, I am due to ride up there for a tour!

        What is the name of your nearest dealer then that deals with Hyos at all ? I could use that info to update the dealer list on this website.

        Things seem to be changing every year lol.
