2023 Yamaha YZ450FX Totalmotorcycle.com Features and Benefits

ENGINE

  • Rearward-Slanted Cylinder Design
    The YZ450FX’s distinct rearward-slanted cylinder design—complete with rear exhaust and forward-mounted down-draft intake system—features a cylinder head that works with the frame geometry for optimized weight distribution. Internally, the engine features a straight intake tract, aggressive cam profiles, a high-compression “box bridge” piston design with DLC-coated piston pin and more. Finally, the YZ450FX features specific ECU settings to suit the needs of cross country riders.
  • Innovative Yamaha Power Tuner App
    The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.
  • Adjustable Engine Mapping
    A handlebar-mounted map switch allows the rider to quickly select between preloaded engine maps—loaded and configured in the Power Tuner App—to account for changing riding conditions. Map 1 provides more responsive, quicker revving engine characteristics while Map 2 provides smoother response, 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 riding conditions.
  • Robust Transmission & Clutch
    The YZF450FX’s wide-ratio 5-speed transmission and durable clutch components enhance cross country performance for confident shifting and more flexible gear selection in open terrain.
  • Electric Starter System
    The YZ450FX features a compact electric starter system to minimize restart delays on track and add convenience everywhere else. Powered by a high-capacity and lightweight four-cell lithium-ion battery, the system adds minimal weight.

 

CHASSIS/SUSPENSION

  • Advanced Bilateral Aluminum Frame
    The upper frame bracing provides rigidity and durability while rear frame spars and cross country-tuned engine mounts centralize mass for the best possible balance of impact absorption, stiffness and rider feeling.
  • Class-Leading Suspension
    The industry-leading, fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional balance between handling and bump absorption for race-winning handling performance. The linkage type rear suspension uses a KYB® shock with specially-tuned damping characteristics to match the YZ450FX chassis with both front and rear system settings for optimal GNCC® performance.
  • 270mm Front Brake
    Large 270mm front rotor coupled with aggressive pad material offer excellent braking performance and feel with exceptional stopping power and controllability.
  • Compact Body & Seat Design
    The YZ450FX features stylish bodywork from tip to tail, including a large 2.15-gallon mass-centralized fuel tank. The body design is narrow for more comfortable knee grip and control feeling while the narrower and lower seat gives the rider additional room to move aboard the machine.
  • Cross Country Wheels & Tires
    The YZ450FX features enduro-specific Dunlop® Geomax MX33 tires for the ideal balance of traction and durability, complete with an 18-inch rear wheel. Each wheel’s cross-sectional profile is computer-designed to shave valuable weight without sacrificing durability.

    The YZ450FX includes a range of cross country specific upgrades compared to the YZ450F motocrosser including a composite engine guard, 18-inch rear wheel, sealed O-ring chain, fuel level warning indicator and a folding aluminum kickstand.
  • Adjustable Handlebar Mounts
    Four-position adjustable handlebar clamps are rubber mounted to improve comfort, reduce handlebar vibration and allow riders to adjust the bar position, while the oversize 1-1/8-inch handlebar is strong but lightweight.
