| 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. | Stiff suspension - This is probably the most common complaint. Riders often mention that potholes and broken roads are felt more sharply compared to scooters like the Activa or Jupiter. Large turning radius - Because of its sporty geometry and longer wheelbase, maneuvering in tight spaces and U-turns can require extra effort. Limited footboard practicality - Unlike conventional scooters, the Aerox has a central tunnel. Owners who regularly carry grocery bags or larger items on the floorboard find this inconvenient. Rear seat comfort - While the rider seat is generally comfortable, some pillion riders complain that the rear seat is a bit high and firm for long journeys. Higher maintenance costs - Compared to a typical 110cc or 125cc scooter, service costs and spare parts can be slightly more expensive due to the liquid-cooled engine and premium components. |
| 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 Version S is a maxi-scooter that combines the convenience of an automatic scooter with engineering elements typically found in Yamaha’s performance-oriented motorcycles. Its design follows a sporty and aerodynamic approach, featuring a sharp front apron, centrally mounted LED headlamp, muscular body panels, and a stepped seat layout. The overall proportions are noticeably larger than those of conventional scooters, giving it a distinctive road presence while also accommodating a sizeable under-seat storage compartment. Powering the Aerox 155 Version S is a 155cc, single-cylinder, liquid-cooled, fuel-injected engine that produces approximately 15 PS of power and 13.9 Nm of torque. The engine incorporates Yamaha’s Variable Valve Actuation (VVA) technology, which adjusts valve timing to help maintain performance across different engine speeds. Unlike smaller commuter scooters that prioritize low-speed operation, the Aerox’s engine is designed to deliver a broader powerband, allowing it to handle city riding as well as sustained highway speeds. Power is transmitted through a CVT automatic gearbox, eliminating the need for manual gear changes and making operation straightforward in varying traffic conditions. The scooter is built around an underbone frame that contributes to structural rigidity and handling stability. Suspension duties are managed by telescopic front forks and twin shock absorbers at the rear. This setup is intended to balance everyday usability with responsive handling characteristics. The Aerox rides on 14-inch alloy wheels at both ends, which are larger than those found on many scooters in the segment. The larger wheel size can influence stability and road feedback, particularly at higher speeds. Braking performance is handled by a front disc brake and a rear drum brake. The scooter is equipped with a single-channel Anti-lock Braking System (ABS) for the front wheel, helping reduce the likelihood of wheel lock-up during sudden braking situations. The Version S variant also features Traction Control System (TCS), a technology that monitors wheel slip and adjusts power delivery when necessary to maintain traction on low-grip surfaces. In terms of features, the Aerox 155 Version S includes a fully digital LCD instrument console that displays information such as speed, fuel level, trip data, and other riding information. Bluetooth connectivity through Yamaha’s Y-Connect application enables smartphone integration, allowing riders to access call alerts, message notifications, maintenance reminders, and fuel consumption data. The Smart Key system offered on the Version S variant introduces keyless operation, enabling ignition control and scooter access without physically inserting a key. The fuel tank capacity stands at 5.5 litres, while the kerb weight is approximately 126 kg. The seat height of 790 mm and wheelbase of 1,350 mm contribute to the scooter’s riding ergonomics and stability. Storage practicality is supported by a large under-seat compartment that can accommodate daily essentials and certain helmet types depending on their size and shape. Additional equipment includes LED lighting throughout, an automatic start-stop system designed to reduce fuel consumption during idle periods, and a side-stand engine cut-off feature. Together, these specifications position the Yamaha Aerox 155 Version S as a feature-rich scooter that blends modern technology, performance-focused engineering, and everyday commuting functionality within a single package. |
| 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 Version S occupies a unique space in the Indian scooter market by combining the practicality of a scooter with performance characteristics that are more commonly associated with entry-level motorcycles. Its 155cc liquid-cooled engine delivers strong acceleration throughout the rev range, while the rigid chassis and larger wheels contribute to confident handling at both city and highway speeds. The riding position feels sporty yet relaxed enough for daily commuting, though the firm suspension setup tends to transmit road imperfections more noticeably on rough surfaces. Features such as traction control, Smart Key technology, and Bluetooth connectivity add to the modern appeal, while the maxi-scooter design provides a distinct road presence. However, the focus on performance and styling does bring certain compromises in everyday practicality, particularly when compared to conventional family-oriented scooters. The Aerox ultimately presents a different approach to scooter design, emphasizing riding dynamics and high-speed composure alongside everyday usability., 4.4, MotoAutiv Team |
