This is because they are built with the quality, reliability and power to endure tough Aussie conditions.

Fuel efficient, high output operations

The GX Engines Precision Camshaft design offers precise valve timing and optimal valve overlap for better fuel efficiency. Drawing on decades of Honda engineering with an OHV design, the GX range delivers increased efficiency and optimal power transfer for where you need it. They also incorporate a high compression ratio for better fuel efficiency than comparable engines, so the GX range will end up lighter on your pocket in the long run.

OHV design

As the name implies, Over Head Valve engines (OHV) have the valves located above the combustion chamber, in the roof of the cylinder head. The Over Head Valve layout permits smoother fuel mixture intake, plus quicker and more complete exhaust. This increased combustion efficiency, in turn, enables a higher compression ratio to be used. In this way it is possible to obtain a greater power output and to avoid the build-up of carbon. The OHV-design gives also an excellent thermal balance, which contributes to reduced cylinder distortion, a decrease in oil consumption and an increase in engine service life.

Smooth operation

A ball bearing-supported crankshaft and precision engineered components result in greater stability and lower vibration for you, no matter what the application. The use of lightweight, noise-reducing materials and a forged steel crankshaft and rigid crankcase results in an exceptionally quiet engine that incorporates a large capacity, multi-chamber exhaust system. With a sophisticated air intake system, oil alert, large fuel tank, easily accessible spark plug and cast iron cylinder sleeve, the GX engine will work as hard as you with minimal fuss - day in, day out.
