Engine/Drivetrain

• Powerful 420cc longitudinally mounted engine eliminates 90° power transfers and boasts exceptional horsepower and torque. Overhead-valve design provides compact engine dimensions for excellent ground clearance
• Cylinder head redesigned with higher compression, revised camshaft profile and larger intake valves (38 vs. 35mm) and exhaust valves (33 vs. 30mm) to ensure strong mid-range and top-end power
• Programmed Fuel-Injection (PGM-FI) features a 34mm 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
• New high-capacity oil system features a high-flow filter and a two-rotor pump to provide oil for the engine and the pressurised transmission clutches
• Rubber-cushion engine mounting and gear-driven counter balancer reduces 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
• New lightweight, automatic transmission offers 5- speed auto-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 rider forgets to downshift when stopping in ESP mode, the transmission downshifts to third gear to prevent engine lugging
• Excellent fuel economy results from the transmission’s high efficiency
• TraxLok 4WD/2WD selector lever allows 4WD or 2WD operation

• Independent double-wishbone front suspension uses premium shock absorbers to provide 160mm of wheel travel for a plush, comfortable ride
• Honda's double wishbone, Independent Rear Suspension (IRS) provides 160mm of wheel travel and minimises geometry variations as the suspension travels through its stroke, maintaining rear wheel alignment, contributing to responsive overall handling, and reducing tire wear and maintenance intervals
• Revolutionary Electric Power Steering (EPS)
• Dual hydraulic front and single rear disc brakes provide exceptional stopping power and feature brake pads that minimise wear from dust and sand
• Rear center disc brake and self-adjusting mechanical rear parking brake are mounted on the rear driveshaft, contributing to the ATV’s considerable ground clearance
• Tough, large-diameter 24x8-12 front, and wide 24x10-11 rear tyres provide excellent ground clearance while maintaining precise handling
