This is an aftermarket 2-piece front brake rotor for first generation KTM Duke 390 or RC390 that have the 300mm rotor from the factory. 2015-2016 model years. Only selling because I ordered the 320mm version and they sent me a 300mm by mistake.
$100 firm.
I do have a genuine Galfer 300mm rotor avail now for $250 as well, see my other ads.
