Comfort & Convenience

  • ELECTRIC STARTER: The electric start system ensures trouble-free starting. It drives the clutch side of the crankshaft, providing superior lubrication to starter gears while allowing a narrow engine with a short, strong crank.
  • GEAR-DRIVEN COUNTERBALANCER: The gear-driven counterbalancer reduces vibration and drives the water pump.
  • SIDESTAND: A sidestand may seem insignificant, but this forged alloy piece is an exceptional example of this bike's attention to detail.
  • SUPERIOR ERGONOMICS: Placing the rider’s legs at the narrowest part of the frame helps improve comfort and handling.
  • FUEL MILEAGE METER: The fuel mileage meter is a key feature that displays current and average fuel mileage and fuel consumption and can show data in miles or kilometers. It's in the same digital display as the speedometer, odometer, tripmeter, and clock.
  • CALIFORNIA GREEN-STICKER COMPLIANT: California riders can ride this bike off-road year-round in any open OHV area since it's Green-Sticker compliant.

Engineering

  • WIDE-RATIO SIX-SPEED TRANSMISSION: Having six speeds in the transmission, as opposed to a typical five on an MX bike, provides more versatility. This bike can handle everything from single track riding to wide-open Baja blasts.
  • LITHIUM-ION BATTERY: Conventional batteries can be heavy, but this premium battery is compact and lightweight, providing excellent performance for your bike.
  • TUNED-WEIGHT CRANK: The bike has a unique crankshaft that differs from our MX and dual-sport models. The crankshaft's weight and inertial characteristics play a big role in power delivery.
  • DUAL RADIATORS: The dual radiators feature a refined core for superior heat dissipation, while the coolant recovery tank is located in front of the engine between frame downtubes for improved center of gravity.
  • TITANIUM FUEL TANK: The premium titanium tank is durable and lightweight, with a capacity of 2.0 gallons.
  • SKID PLATE: The factory skid plate is light, yet it also offers the engine and lower-frame protection that serious riders demand on a machine like this.

Handling

  • TWIN-SPAR CHASSIS: The motorcycle has a lightweight, stiff, twin-spar aluminum chassis with excellent handling. It's wider than the standard MX frame to fit the six-speed transmission.
  • DUNLOP MX52 TIRES: The Dunlop MX52 tires provide excellent off-road traction across various terrains and conditions, making them a critical component for on/off-road bikes.
  • LOW CENTER OF GRAVITY: The Unicam® engine's compact design and our center-of-mass engineering reduce the bike's weight and improve handling.
  • WORKS-STYLE FRONT BRAKE: Improved stopping power and handling thanks to the compact twin-piston front brake caliper, anodized aluminum brake pistons, and lightweight 260mm front disc that minimize unsprung weight.
  • WORKS-STYLE REAR BRAKE: An HRC works-style rear brake system uses a 240mm brake rotor that integrates with the rear master cylinder and fluid reservoir, eliminating the need for a separate reservoir and hose.
  • 18-INCH REAR WHEEL: The 18-inch rear wheel provides a great selection of off-road tires, and the black DID rims add to the aesthetic appeal.

Performance

  • 450CC UNICAM® ENGINE: Honda's Unicam® design creates a compact engine that saves weight. The included valve angle flattens the combustion chamber for easier ignition while the camshaft sits lower, making it more compact and lowering the center of gravity.
  • FUEL INJECTION: Our proven fuel injection system provides excellent torque, spot-on metering, and response, especially in the critical low-rpm range. Additionally, it automatically compensates for changes in elevation and weather.
  • TITANIUM INTAKE AND EXHAUST VALVES: Lightweight titanium intake and exhaust valves permit smaller valve springs, reducing overall engine height.

Style

  • WORKS MX STYLING: The “X” graphics may remind you of our MX bikes because they're derived from them, while the smooth bodywork makes it easy to move around, and the in-mold graphics look cool and are durable, too.
  • FACTORY HANDGUARDS: Designed exclusively for off-road riders and manufactured to Honda standards, these guards protect against rocks, branches, thorns, and brushes while giving the bike a polished look.

Techonology

  • LIGHTING PACKAGE: It has a complete lighting package (headlight and taillight) for improved visibility in low-light conditions.
