A POPULAR CHOICE

Honda’s GX series engines are legendary for superior reliability and performance. Low noise levels, low vibration and low emissions – without sacrificing power output or performance.

Used in construction/industrial equipment and agricultural, it is also a popular choice of engine for commercial lawn and garden equipment.

SMOOTH OPERATOR

A ball bearing-supported crankshaft and precision engineered components result in greater stability and lower vibration.

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, dual element air cleaner and cast iron cylinder sleeve, the GX120 is built durable and tough.

EASY TO USE AND MAINTAIN

With simple throttle control, large fuel tank, large automotive type fuel cap and easily accessible spark plug; Honda engine designers always have the user front-of-mind.
