Description

When you need a small engine that just gets on with the job, the KingTech GX25 25cc 4-stroke delivers. It fires up clean, pulls hard, and sips fuel, so you spend more time working and less time refilling. The oil-immersed timing belt OHC keeps things quiet and precise, while the 360°-inclinable design means you can run it flat, vertical, or upside down without drama. Low vibration from lighter internals cuts operator fatigue on long shifts. With dependable transistorised ignition and a rugged full-cover construction that won’t snag in scrub, the GX25 is a compact power source built for lawn, garden, farm, and site gear. Reliable. Efficient. Ready to work.

Great value

I fitted this engine to an older brush cutter and it brought the machine back to life. Easy starting, reliable operation, and very fuel efficient.

Perfect replacement

Purchased this to replace a worn-out engine. Installation was straightforward and it started on the second pull. Runs smoothly and has plenty of power for its size.
