CRF 400RX ENDURO 2025

Frame and Chassis

• 70% redesigned aluminium twin-spar frame for increased stability and rider confidence

• New upper and lower triple clamps, upgraded front axle, and fork legs

• Completely revised Showa 49 mm suspension front and rear – smooth damping throughout the full stroke

• New dual-piston Nissin front brake caliper (HRC developed) – consistent braking performance even under heat

• Updated Pro-Link rear suspension – increased rigidity and improved bump absorption

• 7.7-litre fuel tank, 18-inch rear wheel, integrated side stand, and handguards – all optimised for enduro use

Chassis Details

• 8% increase in torsional rigidity for improved overall stability

• Balanced torsional/lateral stiffness ratio enhances cornering performance

• Rear subframe mounts to reinforced pivot plates – reducing vibration transfer by 27%

• Reinforced front axle and steering mounts improve stiffness and reduce flex during suspension stroke

• Suspension travel: 310 mm front, 308 mm rear (Showa components)

• New fork oil and spring settings ensure smooth damping across the stroke

• Rear shock removal made easier – only four parts to remove, cutting service time in half

Brakes and Wheels

• New Nissin front brake caliper with reduced heat-induced lever play (57% less at high temperatures)

• Brake discs: 260 mm front, 240 mm rear

• DID black aluminium rims: 21-inch front, 18-inch rear, equipped with Metzeler Six Days Extreme tyres

Ergonomics and Design

• Redesigned bodywork and ergonomics for unrestricted rider movement

• Enduro-specific radiator shrouds for improved cooling and rider comfort

• Integrated LED headlight and reinforced rear fender with license plate holder

• Renthal Fatbar handlebars with four adjustable positions

• Updated CRF family graphics with the Honda Wing logo on the front mudguard

Engine and Performance

• Engine: 412.6 cc, UNICAM, 4-valve, liquid-cooled single-cylinder

• Direct airflow intake improves throttle response and traction at low revs

• Extended exhaust header smooths mid-range power delivery

• Enduro-specific PGM-FI fuel mapping optimised for torque and control

• Heat-treated aluminium muffler compliant with FIM 109 dB noise limits

• Hydraulic clutch with eight-plate design for consistent feel and reduced rider fatigue

• Three ignition maps based on gear position for optimal response in every situation

• Integrated cooling fan ensures stable operating temperatures even at low speeds

Electronics and Rider Aids

• Honda Selectable Torque Control (HSTC) – 3 levels of traction control + OFF

  • Mode 1: Light intervention for dry conditions

  • Mode 2: Balanced control for mixed terrain

  • Mode 3: Strong intervention for mud and slippery surfaces

• HRC Launch Control – 3 selectable modes for different starting conditions

  • Level 1: 9,500 rpm (dry tracks, experienced riders)

  • Level 2: 8,500 rpm (general use)

  • Level 3: 8,250 rpm (mud, beginner riders)

• Engine Mode Select Button (EMSB) – three engine maps

  • Mode 1: Standard

  • Mode 2: Smooth power delivery

  • Mode 3: Aggressive throttle response

• LED indicators on the left handlebar for easy system adjustments
