| Detailed Overview | The BMW M 1000 RR is built around a 999cc water and oil-cooled inline four-cylinder four-stroke engine, sharing its basic architecture with the S 1000 RR but with meaningful internal differences. The cylinder heads are revised with larger 52mm throttle bodies, and the ShiftCam variable intake camshaft system is carried over. The result is 212 hp at 14,500 rpm and 113 Nm of torque at 11,000 rpm, delivered through a six-speed gearbox with a slip-and-assist clutch and a bidirectional quickshifter as standard. Fuel is fed via electronic injection with a variable intake pipe, requiring a minimum of 98 RON premium unleaded petrol. The chassis is a bridge-type cast aluminium frame with the engine serving as a structural element, wrapped around M Carbon wheels, a notable distinction from the standard S 1000 RR’s cast aluminium units. These carbon wheels contribute to the bike’s 192 kg kerb weight, one of the lowest figures in its class. Suspension is handled by a fully adjustable 45mm upside-down fork at the front with 120mm of travel, and a fully adjustable monoshock at the rear with 117mm of travel. Braking is taken care of by twin 320mm discs at the front with four-piston fixed calipers, and a single 220mm disc at the rear with a two-piston fixed caliper, supported by Race ABS Pro as standard. The bike rolls on 120/70 ZR17 front and 200/55 ZR17 rear tubeless radial tyres. Seat height is 832mm with a 16.5-litre fuel tank. The electrical system uses BMW’s M Lightweight lithium-ion battery at 12V / 5Ah, paired with a 450W alternator. The instrument cluster is a 6.5-inch TFT display with full LED lighting and electric start. Electronics include the full Riding Modes Pro suite with Launch Control, Wheelie Control, Pit Lane Limiter, Brake Slide Assist, Slide Control, and a steering angle sensor. The Competition variant adds the M GPS Laptrigger with data logging capability, a lighter anodised swingarm, DLC-coated M Endurance chain, and M milled parts. In India, it was offered in two variants, Standard at ₹49 lakh and Competition at ₹55 lakh ex-showroom, both now discontinued. | 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 M 1000 RR is BMW Motorrad's most extreme road-legal offering, extracting 212 hp from a revised version of the familiar 999cc ShiftCam inline-four. The M Carbon wheels and 192 kg kerb weight give it a noticeably sharp, responsive character, and the Race ABS Pro electronics suite functions cohesively at pace. On track, it is difficult to fault. In India however, the fully committed riding position, heat buildup in traffic, and the bike's narrow performance window make everyday use genuinely demanding. At ₹49–55 lakh ex-showroom, ownership costs, limited trained technicians, and growing parts availability concerns add further weight to the ownership equation., 3.9, 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 |
