The Yamaha Aerox 155 is a scooter from Yamaha. It was launched in 2021 and is still on sale. Scooters are made for easy city riding: automatic, step-through and usually with storage under the seat. With a 155 cc engine it sits in the larger, 150 cc-plus scooter class.
Power comes from a 155 cc single-cylinder liquid-cooled fuel-injected engine that makes 15 PS at 8,000 rpm and 13.9 Nm of torque at 6,500 rpm. Divide power by kerb weight and it has about 119 PS per tonne; by that measure, there is enough go for confident city riding and relaxed highway cruising. The claimed top speed is 111 km/h. It has electric start.
It uses an automatic (CVT) transmission, so there are no gears or clutch to work — you twist the throttle and go.
It is built around an underbone frame. Suspension is by telescopic fork at the front and unit swing at the rear. Braking is by a 230 mm disc at the front and a 130 mm drum at the rear, with single-channel ABS. Single-channel ABS works on the front wheel, which does most of the stopping. It rides on 14-inch alloy wheels with tubeless tyres — 110/80-14 at the front and 140/70-14 at the rear.
The seat is 790 mm off the ground, which is about average and suits most riders. It weighs 126 kg ready to ride. Ground clearance is 145 mm — adequate, though tall speed breakers need care. It is 1,980 mm long, with 1,350 mm between the axles. Its 5.5 L fuel tank and claimed mileage of 40 kmpl work out to roughly 220 km per tankful on paper; real-world range is usually lower.
Equipment includes a digital instrument console, an LED headlamp, USB charging port, call and SMS alerts, mobile app connectivity, daytime running lamps and real-time mileage indicator. Safety equipment includes side-stand warning, engine kill switch, hazard light switch, traction control, low fuel indicator and malfunction indicator.
The manufacturer's warranty is 2 years or 30,000 km. It comes with 4 free services, the first due at 1000 km or 30 days. For the Yamaha Aerox 155, Mechiee offers a fixed ₹1,249 doorstep service.
