2010 Honda FourTrax Rancher AT TRX420FA

FourTrax Rancher AT/FourTrax Rancher AT with Electric Power Steering

The FourTrax® Rancher® AT brings a true automatic five-speed transmission to the popular Rancher lineup that gives the rider the option to choose between a fully automatic mode and Electric Shift Program (ESP®), which allows for easy pushbutton shifting. Consider also an independent rear suspension, selectable 4WD/2WD TraxLok® and a rugged torque-sensitive front differential plus a variation with Electric Power Steering (EPS), and it’s clear there’s no better choice for reliable and rewarding ATV recreation.

There’s a simple reason why Honda’s Ranchers have long been the best-selling line of ATVs in America. First, of course, is the fact that they’re Hondas, with all the legendary dependability and quality our name guarantees. Then there’s the lineup itself, captained by the amazing flagship machine you see here: the Rancher AT. Built around the same class-leading 420cc engine as its sibling Ranchers, the AT takes it up a notch or two, pushing the performance and capability envelope to all-new heights with features like plush Independent Rear Suspension (IRS), Electric Power Steering (EPS), Programmed Fuel Injection (PGM-FI), and a revolutionary, twin-clutch-equipped automatic five-speed transmission that’s arguably one of the slickest- and quickest-shifting gearboxes on dirt. It’s versatile, too, as the Rancher AT lets you choose between going fully automatic or shifting via the push-button Electric Shift Program (ESP).

Is there a better, more capable midsize-class ATV than the Rancher AT? The answer to that should be automatic.

Important Safety Information
Recommended for riders 16 years of age and older. Honda recommends that all ATV riders take a training course and read their owner’s manual thoroughly.

The First of Its Kind. The Quickest, Too.
Exclusive to the Rancher AT, Honda’s revolutionary automatic five-speed transmission features a twin-clutch design that ensures slick, lightning-fast shifts and optimal power transfer.

Twice the Performance. Half the Effort.
Honda’s Electric Power Steering (EPS) features sophisticated torque sensors that measure how much force you’re applying and then tailor how much extra assist you need.

Independent Rear Suspension.
The Rancher AT’s independent rear suspension (IRS) features a double wishbone design that maintains rear wheel alignment for a smoother, more surefooted ride over all kinds of terrain.
