All-new double-cradle steel frame developed with Computer Aided engineering features increased stiffness for even more precise handling and a smoother ride. New mapping for the programmed Fuel Injection (pGM-FI) system improves power delivery and throttle response, and increases fuel economy for greater range. New front and rear suspension systems feature an increase in travel for a plush and controlled ride. Additional Features • Rugged OHV liquid-cooled, fuelinjected 420cc longitudinally mounted engine allows direct driveshaft alignment to both front and rear wheels for maximum drivetrain efficiency. • Overhead-valve design provides compact engine dimensions for excellent ground clearance while maintaining a broad, easy-to-use powerband. • Adjustable spring preload is now featured on all shocks to allow suspension tuning to match varying loads and riding conditions. • New enclosed-axle type swingarm with optimized stiffness for improved toughness and durability, and excellent handling performance. • New rubber swingarm pivot bushings yield increased lowspeed ride comfort and increased durability. • New fuel pump is derived from Honda automobile technology. It mounts in the fuel tank for better heat isolation and offers increased filter life. • Dual front hydraulic disc brakes and sealed mechanical rear drum brake for strong stopping power. • Rear brake is now located inside the right rear wheel for improved durability and increased ground clearance. • New, aggressively styled bodywork also provides better mud and water protection. • The TRX420FM1 offers Honda’s TraxLok® 2WD/4WD system with two drive modes while the TRX420TM1 is two-wheel drive. • Honda’s TRX420TM1/FM1 is formerly the TRX420TM/FM TWO WHEEL DRIVE ATV 420 CC MOTOR.
