| Cons | More expensive than many 125cc scooters, making it a premium purchase. Under-seat storage is smaller than what some rivals offer. Torque and overall performance may feel limited for riders who often travel with a pillion or heavy luggage. Suspension can feel slightly firm for some riders, especially on very bad roads. Service network and parts availability may not be as widespread as mass-market brands. | Firm Suspension Setup - The most common complaint from owners is the stiff ride quality. Rough roads, potholes, and broken surfaces can be felt more noticeably compared to comfort-focused scooters. Limited Floorboard Practicality - Unlike conventional scooters, the Aerox has a central tunnel, which eliminates the flat floorboard. This can reduce convenience when carrying shopping bags or larger items. Large Turning Radius - Some riders find U-turns and tight-space maneuvering less convenient due to the scooter's longer wheelbase and sporty geometry. Premium Pricing - The Aerox 155 is positioned above many mainstream scooters, making it one of the more expensive options in the category. Pillion Comfort Could Be Better - While acceptable for city use, some pillion riders report that the rear seat can feel firm during longer journeys. Heavier Than Typical Scooters - At approximately 126 kg, the Aerox is noticeably heavier than most 125cc scooters, which can be felt while parking or pushing the scooter manually. |
| Detailed Overview | The Aprilia SR 125 is a 125cc scooter that focuses more on performance and handling than typical everyday scooters. It is powered by a 124.45 cc, single-cylinder, air-cooled engine that produces around 10.11 PS and 10.33 Nm, paired with a CVT automatic transmission. This setup gives it a slightly quicker and more responsive feel in city traffic. It can reach a top speed of around 90 km/h, which is in line with most scooters in this segment. One of the key differences is its 14-inch wheels, combined with wide tyres, which help improve stability and control while riding. The suspension setup includes telescopic forks at the front and a rear monoshock, which supports better handling but feels slightly firm on rough roads. Braking is handled by a front disc and a rear drum with a combined braking system. The scooter weighs around 118 kg and has a ground clearance of about 155 mm, which is manageable for most city conditions. It comes with a 6-litre fuel tank, and in real-world use, mileage usually falls between 35 to 40 km/l depending on riding conditions. In terms of features, the SR 125 gets a fully digital instrument cluster that shows basic information like speed, fuel level, and trip data. It also includes LED lighting elements, but does not offer advanced connectivity features. Practical aspects like under-seat storage are limited, and overall dimensions are compact enough for easy city use. The overall setup makes it feel more focused on riding experience and stability rather than comfort and utility. | 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. |
| Expert Review | The Aprilia SR 125 is positioned as a sporty 125cc scooter in India, focusing more on performance and handling than basic commuting needs. Its 124.45 cc engine delivers slightly stronger acceleration compared to typical scooters in this segment, which suits riders looking for a more engaging ride in city conditions. The use of 14-inch wheels and a firm suspension setup gives it better stability on roads, though it can feel slightly stiff over rough surfaces. In terms of features, it remains fairly simple, with a digital display and essential functions rather than advanced connectivity options. Its design and riding posture are closer to a motorcycle-style feel, which appeals to younger riders but may not suit everyone looking for comfort-focused commuting. Practical aspects like storage space and mileage are average for the segment. Overall, its relevance in India comes from offering a different riding experience within the 125cc scooter category, rather than focusing purely on convenience or efficiency., 4.0, MotoAutiv Team | The Yamaha Aerox 155 stands apart from conventional scooters by focusing heavily on performance and handling rather than pure practicality. Its 155cc liquid-cooled engine, derived from the Yamaha R15 platform, delivers strong acceleration, smooth power delivery, and impressive highway cruising ability for a scooter. The chassis feels rigid and composed, while the 14-inch wheels and wide tyres provide a level of stability and cornering confidence that is uncommon in this segment. The Aerox remains one of the few scooters that feels equally comfortable filtering through city traffic and maintaining triple-digit highway speeds. However, this sporty character comes with compromises. The rear suspension is noticeably firm on broken roads, the central tunnel reduces floorboard utility, and the rear drum brake feels less sophisticated than the rest of the package. The feature list, including traction control, Bluetooth connectivity, LED lighting, and Smart Key technology on the Version S, adds a premium touch, but the scooter's overall appeal is defined more by its riding dynamics than by outright practicality. Multiple long-term reviews and owner experiences consistently highlight the Aerox's combination of refinement, high-speed stability, and engaging handling, while ride comfort and everyday utility remain the most frequently cited drawbacks., 4.5, MotoAutiv Team |
