Dimensions in practice
The Aerox 155 weighs 126 kg with fluids, has an 790 mm seat, 145 mm of ground clearance, and rides on a 1350 mm wheelbase. Clearance is on the low side; take tall speed breakers at an angle with a pillion.
The fuel tank holds 5.5 litres, good for about 212 km between fills in real-world riding.
Tyres are 110/80-14 front and 140/70-14 rear, tubeless.
Features, and why each matters
Grouped by what they do for you. Underlined items link to a plain-English explainer.
Safety and braking
ABS on the front wheel only. Far better than none; the rear can still lock.
Front disc brake
Sheds heat and works when wet. Worth the small premium over a drum on any commuter.
Tubeless tyres
A puncture deflates slowly instead of instantly, and roadside repair takes ten minutes.
Traction control
Cuts power if the rear spins on wet paint or gravel. Rare under ₹2 lakh.
Side-stand engine cut-off
Engine will not run with the stand down, which prevents a common low-speed crash.
Hazard lamps
All four indicators flash; useful in fog and when stopped on a highway shoulder.
Chassis
Alloy wheels
Lighter than spoked wheels and they allow tubeless tyres.
Lighting
LED headlamp
Brighter, whiter and lasts the life of the bike. Halogens on rivals look yellow by comparison.
LED daytime running lamp
Makes you visible to cars in daylight, when most two-wheeler collisions happen.
LED tail lamp
Lights up instantly, which gives the vehicle behind a fraction more warning.
Console and connectivity
Digital console
Trip meters, real-time mileage and a gear indicator. The analogue dial is disappearing.
Bluetooth connectivity
Call and message alerts on the console so the phone stays in your pocket.
Convenience
USB charging port
Charges the phone on a long commute. Check whether it is Type-A or Type-C.
Idle start-stop
Engine switches off at signals and restarts on throttle. Worth 3–5% mileage in city traffic.
External fuel filler
Fill up without getting off or lifting the seat. A daily-use feature on scooters.
Under-seat storage
Whether a full-face helmet fits is the question to ask at the showroom.
Equipment against Xoom 160, 450X and Ntorq 150
Against Xoom 160, 450X or Ntorq 150, it gets traction control and external fuel filler that most rivals skip.
What it lacks: turn-by-turn navigation and colour tft console, which rivals at this price offer. None of these are deal-breakers, but they show where the money went.
