If the turn lights speed up their flashing as the revs rise this could be a voltage regulator problem or maybe a flasher relay problem. As the bike is new, I’d contact your dealer as it should be under warranty.
Failing this, put a voltmeter on the 12v battery and rev the engine. Note the max voltage, and post your findings back on here.
Or get hold of a replacement flasher relay (maybe from a donor bike at the dealer) and swap it over to see if the problem goes away.
