The Honda TRX420 Fourtrax ATV is built with all the quality, reliability and advanced features expected of a Honda ATV.
Wider Front Driveshaft Guards
Designed to add even more coverage to the Rancher’s front axles and outboard CV joints, the new guards are another example of how Honda engineers strive to constantly keep improving one of the best ATVs on the planet.
Available with electric power steering (EPS)
Both speed- and torque-sensitive, Honda's Electric Power Steering (on EPS models) excels at reducing steering effort and kickback through the handlebar. It's a big help when riding in ruts, over rocks or on long sidehills. A specially engineered mounting system for the EPS unit increases strength and rigidity.
Comfortable seat
A plush seat and open rider triangle (bar/seat/pegs) teams up with the suspension to really treat you right. Superior ergonomics have always been a Honda priority, and the TRX420 is no exception. With thick, durable foam, it’s exceptionally comfortable.
Longitudinal Engine Layout
By orienting the crankshaft front to back in the chassis in our ATV and side-by-side engines, we route the flow of power straight to the wheels without any unnecessary right-angle detours, reducing powertrain friction and putting more grunt to the ground.
Digital Instruments
Easy to read and full of the information you want. In addition to the standard gear position indicator, speedometer, odometer, trip meter, and hour meter—you get readouts for fuel level, clock, coolant temperature, speed and Honda’s “maintenance minder” system (to help remind you when it’s time to have your ATV serviced).
