What the numbers mean
The 770 mm seat is a middle-of-the-road height: most riders will get the balls of both feet down.
At 135 kg it is manageable at walking pace but heavy enough to notice on a slope.
The 7.1 L tank is typical for the class and enough for a week of commuting between fills. The manufacturer does not publish a consumption figure, so this page does not quote a range.
Tyres are 110/70 - 13 M/C 48P front and 130/70 - 13 M/C 63P rear. Check that your local shop stocks both before a long trip.

Ownership and maintenance notes
- The V-belt and rollers are the parts that change the feel of a CVT scooter. Inspect them at the interval in the owner's manual, and sooner if acceleration flattens or the engine revs without matching speed.
- Engine oil and the air filter do most of the work in keeping a small scooter consistent. Check the oil level cold, on level ground, and use the grade listed for the model.
- YECVT changes the effective ratio electronically. If the scooter feels inconsistent, have the CVT and the electronic control checked together rather than replacing the belt alone.
Source and verification
Figures are taken from Yamaha Motor Indonesia, the Indonesian distributor, on 13 November 2026.

Final drive is inferred from the published layout rather than printed as a separate field.
Wording is quoted as published; spacing and unit symbols are normalised. Specification databases go stale: if a figure here differs from the current distributor page, the distributor page wins, and this sheet records what was published on the verification date.
