With the GX270, you’re looking at one of the best engines in the business. More power. Quieter performance. Lower fuel consumption. Lower emissions. Better features. Exceptional performance. Honda’s GX series lives up to it reputation.

The GX270 is used in all sorts of applications. From pressure washers and construction/industrial equipment to generators and commercial lawncare equipment.


A digital CDI ignition system with variable timing and an increased compression ratio combines with the GX270's Precision Camshaft design to offer 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 use of lightweight, noise-reducing materials and a forged steel crankshaft & rigid crankcase results in an exceptionally quiet engine – an improved piston design reduces mechanical noise, with an overall reduction of engine noise by up to 5dB


The GX270's ball bearing-supported crankshaft, cast iron cylinder sleeve, helical cut gears and precision engineered components result in greater stability and lower vibration for you, no matter what the application.

With a simple throttle control, large fuel tank and automotive type fuel cap, dual oil drains and fills, an easily accessible spark plug and heavy duty recoil starter, the GX270 has it all.

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 also gives an excellent thermal balance, which contributes to reduced cylinder distortion, a decrease in oil consumption and an increase in engine service life.
