Honda 2015 TRX420FA6

Honda TRX420FA6

All-new frame featuring our new independent dual-arm rear suspension (IRS) design with increased travel front and rear for increased confidence and all-day comfort on the trail.



The automatic Dual Clutch Transmission (DCT) provides the compact size and strength of a manual transmission (no belts to slip, break or burnout) with the convenience of an automatic transmission.

Honda’s IRS uses a double-wishbone design with upper/lower A-arms to substantially reduce unsprung weight. The rear knuckle pivots use lightweight metal bushings in place of conventional ball joints and radius arms, eliminating geometry variations as the rear suspension travels through its stroke. This simple design maintains rear wheel alignment and further reduces unsprung weight, contributing to responsive overall handling.

This new independent double-wishbone front suspension gains an additional 2.5cm of travel and the independent dual-arm rear suspension design offers a more optimal shock ratio and increased suspension stroke for a gain of 5.5cm of travel.


Rugged OHV liquid-cooled, fuel-injected 420cc longitudinally mounted engine allows direct driveshaft alignment to both front and rear wheels for maximum drivetrain efficiency.

New mapping for the Programmed Fuel Injection (PGM-FI) system improves power delivery and throttle response, and increases fuel efficiency for greater range.

Electric Power Steering (EPS) system is a next-generation setup that incorporates new ECU mapping for improved linearity in steering response, reduced low-speed steering effort for enhanced manoeuvrability and decreased kickback traits for improved all-around steering action.


New dual-purpose lever makes it easier than ever to engage Reverse gear as well as setting the parking brake. Simply pull the lever to engage Reverse; push the lever to set the parking brake. And the new digital meter display with added functions like a Maintenance Minder system that notifies when it is time for service helps you know exactly what's going on.

Honda TraxLok 2WD/4WD system offers two drive modes: 2WD and 4WD with TraxLok torque-sensing front differential, meaning you can select the right drive mode for any job. With a large 14.7 litre fuel tank you can keep going until the job is done.

With a front carrier capacity is 30kgs and larger rear carrier is 60kgs as well as a 384kg towing capacity getting the heavy lifting done has never been quicker or easier and with 20mm increase in seat thickness you can stay in comfort over those long days on the farm.
