Features May Include:

• YZ450F-Based GNCC® and Hare Scrambles Focused Racer
  The YZ450FX is developed from Yamaha’s flagship motocross model—the YZ450F—with many added features and unique settings that make the YZ450FX the ultimate GNCC®/Woods racer.
• High Performance Four-Stroke Engine
  The compact, powerful YZ450FX engine includes all the same race-developed technologies of the class-defining YZ450F motocrosser, tuned for cross country performance. A host of go-fast innovations include steep valve angles, aggressive cam profiles, high-compression forged piston with low friction rings, high-flow intake and exhaust systems—all thoughtfully packaged to optimize mass centralization.
• Innovative Yamaha Power Tuner App
  Yamaha’s industry-leading Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike for ultimate track-side tuning. Best of all, it's free-of-charge.
• 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.
• Advanced Bilateral Aluminum Frame
  The YZ450FX's advanced aluminum bilateral beam frame features precisely tuned flex characteristics that give riders the ultimate combination of cornering performance, traction feel and bump stability.
• Class-Leading Suspension
  Yamaha's spring-type KYB® forks with refined, speed-sensitive damping and linkage-type rear suspension featuring a KYB® shock endow the YZ450FX with its renowned, class-defining suspension performance straight out of the box.
• High Performance Braking System
  A rigid front caliper and compact rear caliper work with aggressive pad compounds and lightweight rotors to provide exceptional braking power and controllability, dissipate heat more efficiently, and reduce unsprung weight.
• Electric Starter System
  Utilizing a compact starter motor and ultra-lightweight lithium battery, the YZ450FX maintains the convenience of push-button starting for effortless restarts under pressure, and more relaxed riding when the clock isn’t ticking.
• 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 and 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.
• 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 KYB® coil spring-type fork with speed sensitive damping 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 and 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 and Tires
