Product Details

With experience born on the raceways and roadways and a dedication to innovation, there's plenty of reasons to insist on the new Honda GX630 V-Twin engine. There’s superior engine design, with a 90° configuration that reduces vibration and allows a compact footprint. There’s superior construction, with a forged steel crankshaft and an integrated cylinder head. Fewer parts means better durability. There's a digital CDI ignition coil that ensures improved fuel economy and lowered emissions. There's even improved air cleaning, meaning that you can wait 5 times longer between filter changes. Honda even gives their engines a 3-year limited warranty.
