Market and trim notes
This sheet covers the Honda Supra X 125 FI 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.
Honda's Indonesian product API does not publish a seat height for this model, so the field is left blank rather than estimated.

What the numbers mean
At 106 kg (CW)103 kg (SW) it is light enough to push around a workshop or park by hand.
The 4 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 - 17 M/C 38P front and 80/90 - 17 M/C 44P 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.
