What the numbers mean
The 795 mm seat is a middle-of-the-road height: most riders will get the balls of both feet down.
At 118 kg it is manageable at walking pace but heavy enough to notice on a slope.
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 90/80-17M/C (46P) front and 120/70-17M/C (58P) rear. Check that your local shop stocks both before a long trip.

Ownership and maintenance notes
- Clean and lubricate the chain at short intervals in rain or dust, and check slack with the bike on its side stand. A loose chain wears sprockets quickly; a tight one loads the output bearing.
- Check tyre pressures cold. On a light bike a few psi matters more than it does on a car, and it changes both steering and tyre life.
- Liquid cooling adds a coolant level and condition check. Do it when the engine is cold, and never open the radiator cap on a hot engine.
Source and verification
Figures are taken from Yamaha Motor Indonesia, the Indonesian distributor, on 13 November 2026.

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.
