The AK 550 is Kymco's flagship maxi-scooter, a premium grand tourer built around a liquid-cooled 550 cc parallel twin. It pairs a CVT automatic with Brembo front brakes, inverted forks and ABS for a more motorcycle-like ride than typical scooters. It is aimed at long-distance comfort and highway use.
