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 BMW G 310 RR is based on a 312 cc, single-cylinder, liquid-cooled, four-stroke DOHC engine producing approximately 34 PS of power and 27.3 Nm of torque. The engine is paired with a 6-speed manual gearbox featuring an assist and slipper clutch, with power transmitted via a chain drive.

These modes allow the rider to adapt the engine output based on road surface conditions and usage scenarios. The gearbox is designed to provide consistent shifts across different speeds, while the slipper clutch assists in maintaining stability during aggressive downshifting. The chassis is supported by a 41 mm upside-down telescopic front fork and a rear monoshock mounted on a cast aluminium dual swingarm, with preload adjustability at the rear. This suspension setup is configured to manage a combination of urban road irregularities and highway riding conditions. The motorcycle has a kerb weight of approximately 174 kg, contributing to its handling characteristics in both low-speed and higher-speed scenarios. Braking duties are handled by a 300 mm front disc with a four-piston caliper and a 240 mm rear disc, supported by dual-channel ABS. The braking system is designed to provide controlled deceleration across varying road conditions. The motorcycle is fitted with 110/70 R17 front and 150/60 R17 rear tubeless radial tyres mounted on alloy wheels. In terms of dimensions, the BMW G 310 RR has a seat height of 811 mm and a fuel tank capacity of 11 litres.

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. |
