Best of all, it's free-of-charge.
    • Advanced Aluminum Bilateral Beam Frame
      The advanced aluminum bilateral beam frame with YZ450FX-specific engine mounts provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to tackle tight, technical courses with greater confidence.
    • Class-Leading Suspension
      World renowned suspension performance straight out of the box. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption, and now features toolless compression clickers for easy adjustment and new fork covers to help prevent debris damage. The linkage-type rear suspension features a KYB® shock with cross-country focused damping characteristics to match the YZ450FX's refined chassis.
    • High Performance Braking System
      Compact front and rear brake calipers work with aggressive pad compounds and lightweight discs to provide exceptional braking power and control, efficiently dissipate heat, and reduce unsprung weight.
    • Ergonomics Designed for Control
      The YZ450FX's slim, flat, compact body eases rider movement for improved control, including seamless, rounded features from seat edges and side covers to the narrow fuel tank and front shroud. The rider triangle is also designed to provide increased legroom between the seat and foot pegs for enhanced rider comfort.
    • Powerful 450cc Four-Stroke Engine
      Featuring a reversed cylinder head layout, forged aluminum piston, 39 mm titanium valves, lightened crank assembly and dry sump lubrication, the YZ450FX's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.

      Lightweight handlebar-mounted switchgear allows the rider to quickly select between preloaded engine maps"”loaded and configured in the Power Tuner App"”to adjust for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response and slower revving characteristics for when traction is limited.
    • Advanced Fuel Injection
      The engine breathes through a 44mm Mikuni® throttle body fed by a high-pressure electric pump to ensure optimum fuel atomization and power for a wide range of altitudes, weather and riding conditions.
    • Compact Lightweight Clutch
      The YZ450FX's clutch design utilizes a disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smooth engagement and excellent feel.
    • Wide-Ratio Five-Speed Transmission
      The YZ450FX's wide-ratio 5-speed transmission provides a gear for any off-road location, from tight technical sections to open fields and fire roads. The tri-shaft transmission layout vertically stacks the transmission shafts, raising the center shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission.
    • Electric Starter System
      The YZ450FX features a compact electric starter system to minimize restart delays in competition and add convenience everywhere else. Powered by a high-capacity and lightweight four-cell lithium-ion battery, the system adds consistent performance and minimal weight.
