Featuring Variable Valve Actuation (VVA), this engine optimizes valve timing for strong torque delivery at low RPMs and exhilarating acceleration at high RPMs. It produces 15.0 PS (11.0 kW) @ 8,000 RPM and 13.9 Nm of torque @ 6,500 RPM. It is also E20 fuel compatible.
Smart Key with Answer Back Function:
A standout premium feature, the Smart Key system allows for convenient keyless ignition, eliminating the need to physically insert a key. The Answer Back Function helps riders locate their scooter easily in crowded parking lots, adding a layer of sophisticated convenience.

Large 14-inch Wheels with Wide Radial Tyres:
The scooter rides on large 14-inch wheels (110/80-14 front, 140/70-14 rear) fitted with wide radial tubeless tyres. This combination provides excellent grip, enhanced stability, and confident handling, especially around corners and at higher speeds.

The Riding Experience: Pros and Cons for the Premium Performance Scooter Enthusiast
Pros: Why the Yamaha Aerox 155 Ver S Excels
- Sporty 155cc VVA Engine Offers Quick Acceleration: The R15-derived liquid-cooled engine with VVA delivers class-leading power (15 PS) and strong torque, providing thrilling acceleration and making it exceptionally capable for both city and highway riding.
- Excellent Feature List – TCS, Smart Key, SSS, Y-Connect: This “Ver S” variant boasts a comprehensive set of premium features including Traction Control System (TCS) for enhanced safety, a Smart Key with Answer Back function for unparalleled convenience, the fuel-saving Automatic Stop & Start System (SSS), and Y-Connect Bluetooth connectivity for smart integration.
- Futuristic Design with Large 14″ Wheels: Its aggressive, muscular, and aerodynamic maxi-scooter styling, complemented by large 14-inch wheels and wide radial tires, gives it a unique and imposing road presence.
- Spacious Under-Seat Storage & Digital Meter Console: Offers practical storage for daily essentials and a clear, informative fully digital LCD display that enhances the rider’s experience.
- Lightweight and Agile for City Riding: Despite its powerful engine and maxi-scooter dimensions, its 126 kg kerb weight contributes to its agility and ease of handling in congested urban environments.
- E20 Fuel Compatible: Ready for future fuel standards, making it a sustainable choice.
- Premium LED Lighting: Full LED headlights, taillights, and position lights provide excellent illumination and a modern aesthetic.
Cons: Points for Consideration
- Rear Brake is Drum-Type: For a premium performance scooter at this price point, the continuation of a drum brake at the rear, even with front ABS, is a significant drawback compared to rivals offering dual disc setups.
- No Adjustable Rear Suspension: The fixed unit swing rear suspension lacks adjustability, which might limit the ability to fine-tune the ride quality for different rider weights or road conditions.
- Slightly Firm Ride Over Potholes: While offering sporty handling, the suspension setup can feel a bit stiff over very rough patches or large potholes, potentially impacting comfort during extended rides on poor surfaces.
- Not Ideal for Short Riders (790mm Seat Height): The 790mm seat height, combined with its wider profile, can make it challenging for shorter riders to comfortably flat-foot, potentially impacting confidence.
- No Navigation or TFT Screen: While Y-Connect provides smartphone connectivity, the digital LCD screen doesn’t offer turn-by-turn navigation directly on the display, and it’s not a full-color TFT unit, which some competitors are now beginning to offer.
- Fuel Tank Capacity Could Be Larger (5.5 Litres): The relatively small fuel tank might necessitate more frequent fuel stops, especially for those with longer commutes or who frequently ride for extended periods.
- No Dual Channel ABS: While it has single-channel ABS, some premium motorcycles and even a few scooters in similar price ranges offer dual-channel ABS for enhanced safety.
- Pillion Comfort: The stepped-up pillion seat design might not be as comfortable for long journeys with a passenger compared to more family-oriented scooters.

Who Might Consider Other Options?

- You Are a Shorter Rider: The 790mm seat height might be a concern for comfortably flat-footing.

- You Prefer a Softer Suspension Setup: If your daily commute involves very rough roads and ride comfort is a top priority over sporty handling.
