What the numbers mean
The 780 mm seat is a middle-of-the-road height: most riders will get the balls of both feet down.
At 101 kg it is light enough to push around a workshop or park by hand.
The 4.2 L tank is small, in keeping with a short-range commuter; expect regular fuel stops on longer rides. The manufacturer does not publish a consumption figure, so this page does not quote a range.
Tyres are 70/90-14 34P - Tubeless front and 89/90-14 40P - Tubeless rear. Check that your local shop stocks both before a long trip. Small rims are less widely stocked, so confirm availability locally.

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.
- Air-cooled engines rely on clean fins and a clear path for air. Wash the fins gently, and do not let mud or a loose cover block them in traffic.

Cooling, 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.
