2010 Honda FourTrax TRX420PG Canadian Trail Edition

The Honda TRX420PG Canadian Trail Edition with Electric Power Steering (EPS) combines a sporty personality with utility capability unlike any other mid-size ATV. It’s comfortable, thanks to its Independent Rear Suspension (IRS) that’s designed to soak up bumps while maintaining the low centre of gravity, minimal body roll and overall stability that Honda ATVs are famous for. And we know recreational riders are really going to love the TRX420PG’s innovative twin-clutch automatic transmission — it gives you the performance, durability, efficiency and direct feel of a manual transmission with the ease-of-use of an automatic.




Powerful 420 cc longitudinally mounted engine eliminates 90-degree power transfers and boasts exceptional horsepower and torque. Overhead-valve design provides compact engine dimensions for excellent ground clearance.

Cylinder head has been redesigned with higher compression, revised camshaft profile and larger intake valves (38 mm vs. 35 mm) and exhaust valves (33 mm vs. 30 mm) to ensure strong midrange and top-end power.

Programmed Fuel-Injection (PGM-FI) features a 34 mm throttle body, 12-hole Denso injector, and Idle Air Control Valve (IACV) for crisp performance, excellent economy and trouble-free operation in cold conditions and varying altitudes.

Large 7.2-litre airbox with washable, reusable foam air filter provides more air to the engine for increased performance.

High-capacity oil system features a high-flow filter and a two-rotor pump to provide oil for the engine and the pressurized transmission clutches.

Rubber-cushion engine mounting and gear-driven counterbalance shaft reduce vibration.

Large radiator with cooling fan ensures optimal engine cooling under difficult operating conditions.

Stainless-steel exhaust header and muffler for superior corrosion resistance.

Three-chamber muffler baffling uses no packing material that can blow out, providing long-lasting performance.

Lightweight automatic high-efficiency transmission offers five-speed automatic shifting or push-button manual shifting with Honda’s Electric Shift Program (ESP). After the heavy duty centrifugal clutch engages, two Electronic Control Module (ECM)-controlled clutches mounted in the gearbox upshift/downshift to provide smooth, lurch-free shifts. When descending hills in automatic mode, the transmission downshifts, providing excellent engine braking. If the rider forgets to downshift when stopping in ESP mode, the transmission downshifts to third gear to prevent engine lugging.

4WD/2WD selector lever allows 4WD or 2WD operation.



Fully independent front and rear suspension incorporates special calibration developed from extensive testing on Canadian trails.

Honda’s double-wishbone Independent Rear Suspension (IRS) provides 160 mm (6.3 inches) of wheel travel and minimizes geometry variations as the suspension travels through its stroke, maintaining rear wheel alignment, contributing to responsive overall handling, and reducing tire wear.

Independent double-wishbone front suspension uses premium shock absorbers to provide 160 mm (6.3 inches) of wheel travel for a plush, comfortable ride.

Rugged frame and suspension provide an exceptional 231 mm (9.1 inches) of ground clearance.

Honda’s revolutionary Electric Power Steering (EPS) system monitors steering torque and vehicle speed to adjust the levels of steering assist and feel. When stopped or at low speeds, it provides more assistance for light steering effort. As speed increases, the amount of assistance is reduced to provide the appropriate level of feedback. Perhaps the most significant benefit is that the system will provide light and consistent steering feel in both 2WD and 4WD operation. As a secondary benefit, the EPS system acts as a steering damper to greatly reduce undesirable kickback through the handlebars in rough or rocky terrain, thereby helping to reduce rider fatigue.

Dual hydraulic front and single rear disc brakes provide exceptional stopping power and feature brake pads that minimize wear from dust and sand.

Rear centre disc brake and self-adjusting mechanical rear parking brake are mounted on the rear driveshaft, contributing to the TRX420PG’s considerable ground clearance.

Tough large-diameter front and rear tires provide excellent ground clearance while maintaining precise handling.
