The Yamaha Aerox 155 S is a “maxi-scooter” that blends scooter convenience with performance and sporty DNA. With a 155 cc liquid-cooled engine, automatic transmission, and features like smart key/remote start (on S variant), it aims to deliver the practicality of a scooter with the punch and feel closer to a motorcycle — ideal for Kolkata’s city commutes, occasional highways, and riders wanting an upgrade over basic scooters.
