Make light work of hard tasks.
Honda applied our superior engine technology to create the world’s first 360° inclinable 4-Stroke engines. The ultra-lightweight GX Mini 4-Strokes effectively deliver the kind of efficient, cleaner, powerful and quiet performance that you’d expect from a larger engine – but in a very compact package.
Common Applications
