The NMAX 155 is Yamaha's Blue Core maxi-style scooter, popular in Southeast Asia and Europe, built around a liquid-cooled 155 cc single with variable valve actuation on later versions. The generation that arrived for 2020 brought sharper styling, a larger 13-inch wheel setup, ABS and a smart-key option. It is a comfortable, nimble commuter with good under-seat storage.
