Which NMAX does this page cover?

This page covers the Yamaha NMAX 155 STD with a conventional ignition key, supplied by Niroomotor. If the scooter you are considering has a different name, equipment or production year, do not assume that this table applies to it simply because it is called "NMAX 155". The source does not identify the exact year of the version described.

According to the supplier, this model has a 155 cc engine, CVT transmission, liquid cooling and a 7-litre fuel tank. CVT means that you do not need to change gears manually while riding. The source lists disc brakes at the front and rear on this version; disc brakes alone do not establish the presence of ABS.

Which specifications remain unconfirmed?

The initial information lists a "manual clutch" alongside CVT transmission and gives the wheelbase as "135 mm". Do not treat either as a confirmed specification for this scooter.

The power and torque figures checked on October 11, 2026 also differ from the previous version of the source, and their units are unclear in the newer listing. Until documentation for this exact trim is available, we do not use those figures to compare power or acceleration. Today's source clearly states the battery specification as "12 volts, 6 amp-hours". This revision checks the supplier's information; it is not the result of a real-world motorcycle test.

What should you check before buying?

First record the exact trim name and year of the scooter you intend to buy. Then check the following during the viewing:

Sit on the scooter to assess your reach to the handlebars and the available foot space.
If you usually carry a passenger, also check their seating position and foot space.
Ask a mechanic or service centre about service costs and timing for that version, and the availability of wear parts.
For a used example, have a mechanic perform the inspection rather than relying on a clean appearance.

The specification table does not replace these checks; it helps you ask more precise questions.

Sources and review method

The NMAX information was checked against the supplier's official page on October 11, 2026. Specifications may vary by trim, year and market. Where information is contradictory or lacks units, we have not invented replacement figures. This page does not include road-test experience or an independent assessment of ride quality.

About this model

The Yamaha NMAX 155 STD with keyed ignition is a 155 cc scooter with CVT transmission, liquid cooling and a 7 L fuel tank. These specifications concern this particular version; the source does not identify its model year.

Reviewed on 11 October 2026: NMAX 155 STD with keyed ignition. The source does not identify the exact model year.
Clutch: the previous source entry said 'manual' alongside a CVT transmission. The contradiction means this has been excluded from confirmed specifications; clutch type needs confirmation.
Wheelbase: the previous record and source both stated 135 mm. The correct figure is unknown; it has not been guessed to be 1,350 mm.
Maximum power: the previous record stated 10.3 hp. On 11 October 2026 the source stated '9.9/7760' without units. A confirmed power figure has been withheld until documentation for this exact version is available.
Torque: the previous entry stated '13.57 newtons per metre'. On 11 October 2026 the source stated '13.9/6528' without units. A correct value or unit has not been guessed.
Battery: the previous entry stated '6 amperes per hour'. The supplier's explicit '12V-6Ah' statement supports the corrected display of 12 V, 6 Ah. This is a supplier statement checked on 11 October 2026, rather than an independent measurement.
