If you get no joy from your dealer/importer/distributer, send off an email to KR Motors for some assistance.
It seems there is no one interested in answering in Korea, either.
So .... I am stuck with my bike being held for 10 days now in my local (and only) dealer's garage/workshop as they claim they haven't received an ECU reader yet... The warranty says they have 21 days for repair/reply, after that time they are bound to give me a full refund of its price or a new bike. Knowing the Polish market (it is a wild wild west) and inefficiency of the Polish juridical system (5 or 6 years for a civil case to be heard), they will play with me, as there seems to be no party interested in helping/solving the simple issue here.
I just wonder how Hyosung wants to enter an EU market when they just do not care about their customers at all?! Having a "bad press" at the beginning of their appearance here is like shooting own back with a bow, with a poisoned and jagged arrow...
