Market and trim notes
This sheet covers the Kawasaki Z900 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 810 mm seat is on the tall side for shorter riders, so try it before buying.
At 213 kg it is heavy: use the side stand deliberately and avoid loose surfaces at low speed.
The 17 L tank is touring-sized, which matters more on a bike that can sit at highway speed. The manufacturer does not publish a consumption figure, so this page does not quote a range.
Tyres are 120/70ZR17M/C (58W) front and 180/55ZR17M/C (73W) 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 Kawasaki Motor Indonesia, the Indonesian distributor, on 13 November 2026.
Source page: kawasaki-motor.co.id/id-id/sepeda-motor/z/supernaked/z900/2026-z900.
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.
