Get it done

With its rugged next-generation styling, the Honda Fourtrax 420 offers exceptional pulling power, all-weather easy starts and quick acceleration, delivered by a fuel-injected, liquid-cooled 420cc engine. It also features a beefy 5-speed gearbox. For stopping power to match, dual front hydraulic disc brakes with disc covers incorporate patented built-in scrapers that remove mud and snow from inside the front wheel. Easy to maintain and handle, the Fourtrax 420 is fun to ride with all the reliability you would expect from a Honda ATV.

The Honda difference

An engine that's always good for the job.

The engine is longitudinally-mounted. With the crankshaft in line with the frame you get direct driveshaft alignment to the wheels, improved drivetrain efficiency and a low centre of gravity. And it’s a major contributor to great stability, handling and balance. All features you expect of a Honda ATV.

Safety first

It's always Safety First when we build our ATVs. We hope it's the same when you ride them.

Since our customers aren’t as indestructible as our machines, here are some basic pointers on ATV safety.

Always wear a helmet, gloves and boots as a bare minimum and other protective gear as required. Never ride under the influence of alcohol or other drugs; and never carry a passenger unless your machine has been specifically designed to do so.

Please bear these things in mind – then you can be sure the ATV that’s making your life easier will carry on doing just that.
