Meet the world’s lightest OHC engine. Honda applied decades of superior engine technology to create the world’s first 360В° inclinable 4-Stroke engines.
Perfect for powering Commercial Lawn & Garden Equipment, The ultra-lightweight GX25 Mini 4-Stroke engine efficiently delivers the kind of efficient, clean, powerful, quiet performance that you’d expect from a larger engine – but in a very compact package.The GX25 is also well-known for powering Tillers/Cultivators, Water Pumps, Agricultural Equipment and Construction/Industrial Equipment.When you see the GX25 powering Honda-branded handheld equipment like brushcutters and blowers, you know you’re getting a premium engine.
The world’s lightest OHC engine, the Honda Mini 4-stroke engine requires no fuel/oil mixing, and runs at approximately half the operating cost of comparable 2-stroke engines.A full 360В° “any-side-up” operation means you can use and store the GX25 in any position, and take advantage of the exclusive rotary-slinger lubrication system.The carburetor is equipped with an accelerator pump for fast, easy acceleration, and an efficient port configuration and large diameter valves maximise power output.
An exhaust decompression system and unique low inertia design means the GX25 engine will start first time, every time.There’s an easily accessible spark plug, and it’s simple to drain and re-fill the oil, so maintenance is a piece of cake.High quality materials, fit, and finish ensure that your GX25 Mini 4-Stroke can be relied upon whenever you need it.
3 YEAR WARRANTY
The GX25, like so many other Honda Engines, is covered by a comprehensive Domestic & Commercial 3 Year Warranty.Special designs for horizontal and vertical applications are also available, so whatever your application, the GX25 will deliver.And you’re backed up by over 400 authorised Honda dealers around Australia who are on call to support you if you need repair, maintenance or parts assistance.
