Yamaha Aerox 155 S Review: Sporty Scooter with Serious Punch

The Yamaha Aerox 155 S is Yamaha’s performance-oriented maxi-scooter that brings the spirit of a sportbike into an automatic package. With an R15-derived engine and aggressive styling, it stands out in a crowded scooter market. This review explores how it balances sporty power, city usability, and advanced features.

Engine & Performance

Under its sleek body, the Aerox 155 S packs a 155 cc, liquid-cooled, SOHC engine that delivers 15 PS at 8,000 rpm and 13.9 Nm of torque at 6,500 rpm.
This powerplant, borrowed and tuned from the R15 platform, gives the scooter a lively mid-range punch. As per the first ride reviews, the throttle is crisp and responsiveness is high, making it a thrill in city traffic.
ZigWheels recorded acceleration figures of 0–60 km/h in about 6.26 seconds, making it one of the quickest scooters tested.
In terms of fuel efficiency, Bajaj Finserv claims a mileage of ~48.6 km/l, while other reviews suggest a real-world range around 40–45 km/l. 

Chassis & Handling

The Aerox 155 S sits on a rigid underbone frame and runs on 14-inch alloy wheels wrapped in wide rubber — 110/80 at the front and 140/70 at the rear.
Suspension comes via telescopic forks up front and a unit swing at the rear.
This setup gives the scooter sharp handling and a composed feel even at triple-digit speeds. Reviewers praised its stability on highways and agility in corners.
However, the ride can feel a little firm — especially over potholes or rough patches — due to the stiffer suspension tuning.

Braking is handled by a 230 mm front disc and a rear drum brake, with single-channel ABS for added safety.

Technology & Features

Yamaha hasn’t skimped on modern tech. The Aerox 155 S gets:

• A fully digital LCD instrument cluster, which shows VVA (Variable Valve Actuation) active when applicable.
• Y-Connect app integration, enabling smartphone connectivity, last-parked location, and call/SMS alerts.
• Automatic start-stop system (Smart Motor Generator) for fuel savings in traffic.
• LED lighting for headlamps and tail lamps.
• Under-seat storage capacity of 24.5 litres, which is generous for a sporty scooter.

Practicality & Ownership

With a fuel tank of 5.5 litres and average fuel efficiency, the Aerox can deliver a practical real-world range for daily commuting.
However, as some owners note, the firm suspension can make long rides tiring, and the footboard area sacrifices space due to the sport frame.
On the comfort front, pillion seating has been criticized by some: the seat is relatively small and not the plushest, making it less ideal for long two-up trips.

Design & Styling

The Aerox 155 S deliberately channels sporty DNA in its aesthetics. Sharp lines, an aggressive front end, and a tail section reminiscent of a sportbike give it a distinct presence. Its large 14” wheels further accentuate its performance-oriented look.
The build quality is generally praised as premium, though some owners have mentioned minor panel noise and plastic quality issues.

Conclusion

The Yamaha Aerox 155 S is tailored for riders who want the excitement of a performance bike in the convenience of a scooter. Its R15-based engine, sharp handling, and modern connectivity make it ideal for enthusiasts who mostly commute but still crave spirited rides. While it isn’t the most plush or storage-friendly scooter, its athletic character, power delivery, and premium feel deliver excellent value for those prioritizing performance and style. For anyone who values sporty dynamics in daily transport, the Aerox 155 S is a compelling choice.
