The GX100 engine is frequently used by customers in commercial lawn and garden equipment.

The GX100 engine is suitable for a wide range of heavy-duty applications, construction equipment, portable generators, pumps and other industrial applications.


A ball bearing-supported crankshaft and precision engineered components result in greater stability and lower vibration making it easier to use over prolonged periods of time.

The use of lightweight, noise-reducing materials and a forged steel crankshaft & rigid crankcase results in an exceptionally quiet engine that incorporates a large capacity, multi-chamber exhaust system.

And with a sophisticated air intake system, oil alert, large fuel tank, easily accessible spark plug and cast iron cylinder sleeve, the GX100 will work as hard with minimal fuss.


The GX100's Precision Camshaft design offers precise valve timing and optimal valve overlap for better fuel efficiency.

It draws on decades of Honda engineering with its OHV design, delivering increased efficiency and optimal power transfer for where you need it.

And the GX100 incorporates a high compression ratio for better fuel efficiency.
