The Yamaha Aerox 155 is a maxi-scooter that brings together scooter practicality and motorcycle-inspired engineering in a package designed for both urban commuting and higher-speed riding. Unlike conventional scooters that primarily focus on convenience and comfort, the Aerox 155 incorporates several performance-oriented components, giving it a distinct identity within the Indian scooter market. Its design features a sharp and aerodynamic body structure, aggressive front styling, twin LED headlamps, sculpted side panels, and a stepped seat arrangement that reflects its sporty character. The overall proportions are larger than those of most traditional scooters, contributing to its maxi-scooter appearance and road presence.
At the heart of the Yamaha Aerox 155 is a 155cc, single-cylinder, liquid-cooled, fuel-injected engine. This powerplant produces approximately 15 PS of power and 13.9 Nm of torque and is paired with a continuously variable transmission (CVT). The engine incorporates Yamaha’s Variable Valve Actuation (VVA) technology, which adjusts valve timing according to engine speed to maintain performance across a wider rpm range. This allows the engine to deliver smooth low-speed operation in city traffic while retaining strong performance at higher speeds. Fuel injection technology further helps optimize throttle response, fuel delivery, and engine efficiency under varying riding conditions.
The Aerox 155 is built on an underbone frame that contributes to structural rigidity and handling stability. One of its notable characteristics is the use of 14-inch alloy wheels at both the front and rear, which are larger than those found on many scooters in the segment. These larger wheels work alongside wide tubeless tyres to enhance stability, road grip, and overall handling dynamics. Suspension duties are handled by telescopic front forks and twin rear shock absorbers, forming a setup intended to balance comfort and riding control across different road conditions.
Braking performance is managed by a front disc brake and rear drum brake combination. The front wheel is equipped with a single-channel Anti-lock Braking System (ABS), which helps reduce the chances of wheel lock-up during sudden braking situations. The scooter also includes a Traction Control System (TCS), a feature that monitors wheel slip and adjusts power delivery when traction levels are reduced, particularly on slippery road surfaces.
The Yamaha Aerox 155 offers a fuel tank capacity of 5.5 litres and has a kerb weight of approximately 126 kg. Its seat height of 790 mm makes it accessible to a broad range of riders, while the long wheelbase contributes to stability during higher-speed riding. The scooter also provides approximately 24.5 litres of under-seat storage space, allowing riders to carry daily essentials and certain helmet types depending on their dimensions.
Technology plays a significant role in the Aerox 155 package. The scooter features a fully digital LCD instrument cluster that displays speed, fuel level, trip information, and other riding data. Bluetooth connectivity through Yamaha’s Y-Connect application allows riders to access call alerts, message notifications, maintenance updates, fuel consumption statistics, and smartphone connectivity functions. The Version S variant additionally includes a Smart Key system, enabling keyless ignition and other convenience features.
Additional equipment includes full LED lighting, an automatic start-stop system designed to reduce fuel consumption during idle periods, a side-stand engine cut-off function, and an electric starter system. These features contribute to the scooter’s modern equipment list while supporting everyday usability.
Overall, the Yamaha Aerox 155 combines a liquid-cooled VVA engine, large wheels, traction control, ABS, modern connectivity features, and maxi-scooter styling into a package that differs significantly from conventional commuter scooters. Its specifications emphasize performance, stability, and technology while retaining the practicality expected from an automatic scooter.
