Easy On Your Pocket, Hard-Working:

A digital CDI ignition system with variable timing and an increased compression ratio combines with the GX390'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 where and when you need it.

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 mechancal noise, with an overall reduction of engine noise by up to 5 dB.

Proven Reliability:

The GX390 offers precision-engineered components resulting in lower vibration, and a Ball Bearing-supported Crankshaft for greater stability. It also offers an improved piston design and a heavy duty balancer shaft to deliver smooth performance.

Helical cut gears, a large capacity, multi-chamber exhaust system and sophisticated air intake system also makes for an exceptionally quiet engine.

And with Oil Alert, 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 GX390's features go on and on.
