The Suzuki FX125 is an underbone motorcycle manufactured in Malaysia from 1998, with a powerful four-stroke engine.

It was sold mostly in Malaysia and Vietnam, and in small numbers in New Zealand and Greece.

It uses a five-speed 125 cc (7.6 cu in) DOHC four-valve single-cylinder engine.

Other features include rear monoshock rear suspension, lightweight chassis construction, 17-inch alloy cast wheels (or, on some FX125s, spoked wheels) and a front disc brake, most of which are rarely found in underbones.

The dash unit has an analogue speedometer and indicator lights for the turn signal, high beam, top gear and neutral.
