NEW DELHI: Yamaha's Aerox 155 brochure lists a 230 mm front disc, a 130 mm rear drum and single-channel ABS. It also lists traction control as separate equipment. The distinction matters when reading the scooter's safety specification: the presence of traction control does not turn the braking system into dual-channel ABS.
| Aerox 155 equipment | Official specification |
|---|---|
| Front brake | 230 mm disc |
| Rear brake | 130 mm drum |
| ABS | Single channel |
| Traction control | Equipped, intended to reduce rear-tyre slippage |
| Front tyre | 110/80-14M/C 53P, tubeless |
| Rear tyre | 140/70-14M/C 62P, tubeless |
Read the brake specification wheel by wheel
The brochure identifies the disc and ABS together at the front. At the rear, it specifies a drum. That is the equipment buyers should expect to identify on a matching scooter, rather than assuming that a sporty body and a large rear tyre imply a rear disc brake.
The diameter measurements describe components. They are not stopping-distance figures, and the brochure does not supply a measured emergency-stop result alongside them. It would therefore be wrong to translate the front disc size into a promise about how many metres the Aerox will take to stop on an Indian road.
Single-channel is an important qualification to retain in a comparison table. Removing it and writing only ABS makes the equipment harder to compare accurately with a scooter that has a different system. The precise label is more useful than a broad safety tick in a list of features.
Traction control has its own description
Yamaha describes the traction-control function as reducing rear-tyre slippage. It is listed separately from the front disc and single-channel ABS. Read those as separate entries with separate purposes, rather than counting their names as interchangeable descriptions of the same hardware.
The brochure does not establish a guaranteed grip level for every road surface. Nor does it supply a distance, speed or road-condition threshold within which the rider can depend on intervention. Such operating details should come from the matching owner's manual, rather than being inferred from a promotional description.
A useful showroom explanation should identify the relevant dashboard indications and the information in the supplied manual. Owners should not have to discover what an unfamiliar symbol means during their commute. Equally, a public-road demonstration that deliberately provokes a loss of grip is unnecessary for understanding the equipment list.
The tyres are different front and rear
The official specification gives the front tyre as 110/80-14M/C 53P and the rear as 140/70-14M/C 62P, both tubeless. Retain the complete markings when recording the scooter's specification. Reducing them to a statement that it has large wheels loses the distinction between the front and rear fitments.
For an owner preparing for replacement, a photograph of each sidewall and the corresponding manual entry makes a clearer record than relying on memory. The brochure establishes the listed factory sizes; it does not, by itself, approve an alternative tyre merely because it can be fitted to the wheel.
The rear tyre's width is a visible part of the Aerox's appearance, but appearance does not establish how the scooter will behave on every surface. A tyre specification and an electronic rider aid should not be treated as a guarantee against the effects of poor road conditions.
Match the scooter to the documentation
Aerox material covers both the model family and the Version S equipment package. Confirm the exact version and the supplied documentation before transferring a feature from one brochure or photograph to another vehicle. This is especially useful when viewing a showroom scooter alongside a different colour or edition online.
Our Aerox Y-Connect guide covers phone connectivity separately. Connected functions do not change the brake hardware specified in the brochure. Treating each area separately helps a buyer ask clear questions rather than receiving a general description of a feature-rich scooter.
The Aerox VVA explainer addresses engine operation, while the Aerox storage guide looks at carrying space. Neither should substitute for checking the braking and tyre entries on the vehicle being delivered.
What to record at handover
For the braking equipment, record the model version, confirm the visible front disc and rear drum, and have the dashboard indications explained. Keep the owner's manual with the vehicle documents so that operating instructions can be checked against the correct scooter later.
The Aerox's specification is quite clear when its qualifications are preserved: a 230 mm front disc, a rear drum, single-channel ABS and a separately listed traction-control function. That is a more useful description for an owner than simply calling the scooter equipped with electronic safety features.
