Market and trim notes
This sheet covers the Kawasaki Z125 Pro as listed in the Indonesian distributor’s current catalogue. Market-specific equipment can differ from the same nameplate in another country, so the figures are not interchangeable.

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 7.4 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 100/90-12 49J front and 120/70-12 51 L 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
- 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.
- 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.
Source and verification
Figures are taken from Kawasaki Motor Indonesia, the Indonesian distributor, on 13 November 2026.
Source page: kawasaki-motor.co.id/id-id/sepeda-motor/z/mini-naked/z125-pro/2026-z125-pro.
The source page is the 2026 model-year page.
Cooling 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.
