Features

New for 2024

  • All-New 450cc Four-Stroke Engine Lighter, more compact with increased power across the entire rev range, the all-new 450cc engine maintains the previous YZ450FX model's exceptional pulling power and renowned ease-of-use, with ECU settings tailored to enhance low-end tractability and a 500 rpm higher rev limit for even more top-end power.
  • All-New Aluminum Bilateral Beam Frame A redesigned aluminum bilateral beam frame with YZ450FX-specific front 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 trail sections with greater confidence.
  • New Compact Lightweight Clutch The all-new clutch design replaces the coil springs of the previous model with a new 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. Premium clutch cover employs a stylish geometric design that helps minimize scratching and lends a bold look.
  • New Wide-Ratio Five-Speed Transmission All new 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. Gear ratios are optimized for cross country conditions.
  • New Yamaha Power Tuner App Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App is revised to be even more user-friendly. New features include an intuitive “Simple Tuning” slide bar for engine mapping, three-level Traction Control, a lap timer, and helpful engine and suspension tuning guides.
  • Revised Suspension with Toolless Fork Adjustment The YZ450FX's front fork now features a new hand operated compression clicker for simple, toolless adjustments. Front fork and rear shock settings are optimized for cross country competition. A 10mm lower seat height than the YZ450F provides a lower center of gravity for improved low-speed maneuverability.
  • Slimmer Body & Improved Ergos A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud. The rider triangle is also improved with increased legroom between the seat and footpegs, and revised handlebar position for a more natural posture and enhanced rider comfort.
  • The Ultimate Open Class Cross Country Racer Based on the benchmark-setting YZ450F motocrosser, the all-new YZ450FX is designed to dominate cross country competition. Lighter, more compact, with improved rider ergonomics, revised chassis, more powerful engine and next-generation Yamaha Power Tuner app all carry over directly from the YZ450F. Additional modifications tailored toward enhanced XC performance include a wide-ratio transmission, larger fuel capacity, 18-inch rear wheel, side stand, skid plate, revised ECU and suspension settings, along with a 10mm lower seat height for increased maneuverability in challenging off-road conditions.

Top Items

  • All-New Aluminum Bilateral Beam Frame A completely redesigned 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 trails 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 new 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.
  • New High Performance 450cc Four-Stroke Engine The completely redesigned 450cc liquid-cooled DOHC four-stroke engine is lighter, more compact and features stronger pulling power across the entire rev range. The rev limit is also increased by 500 rpm for longer over-rev, further boosting the YZ450FX's broad power character.
  • New Yamaha Power Tuner App Yamaha’s industry-leading Power Tuner App has been extensively updated, retaining the full functionality of the previous version but now even easier to understand, easier to use, with more functionality. Engine mapping can now be made using an intuitive new slide bar. There is also a new lap timer, Traction Control tuning, and bike set-up guides. Best of all, it's free-of-charge.
  • Slimmer Body & Improved Ergos A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud.

Additional Items

  • Embedded Graphics Premium embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
  • GNCC® Focus The YZ450FX includes a range of cross country specific upgrades compared to the YZ450F motocrosser including a larger 2.1-gallon fuel capacity with level warning indicator, 18-inch rear wheel, composite engine guard, sealed O-ring chain and a folding aluminum kickstand.
  • Race-Winning Details The YZ450FX boasts a wide range of additional top-spec details carried over from the competition-tested YZ450F including rubber-mounted, four-position adjustable handlebar clamps, 1-1/8-inch aluminum tapered handlebars, wide footpegs with new lightweight aluminum alloy mounting brackets and a quick-adjust clutch perch.

Chassis and Suspension

  • All-New Aluminum Bilateral Beam Frame Striking the perfect balance of precise cornering performance and handling stability, the redesigned aluminum bilateral beam frame consists of more than 10 different aluminum components welded together with YZ450FX-specific XC-tuned engine mounts. The result is a better handling machine with lighter feel, improved bump absorption and increased traction, allowing the rider to enter corners with greater confidence and more line choices.
  • 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, and now features a new hand operated compression clicker for toolless adjustments. The linkage type rear suspension uses a KYB® shock with specially-tuned damping characteristics to match the YZ450FX chassis. New settings also result in a 10mm lower seat height than the YZ450F and lower center of gravity for excellent cornering performance and rider comfort in technical sections.
  • Cross Country Wheels & Tires The YZ450FX's 18-inch rear wheel comes laced with a three-cross-spoke pattern for improved impact absorption and rider feel. Wheels come wrapped in Dunlop® Geomax MX33 tires for an ideal balance of traction and durability.
  • High Performance Braking System A large 270mm front brake disc and 240mm rear are coupled with high performance Nissin caliper and aggressive pad material to provide exceptional stopping power and control.
  • Slimmer Body & Improved Ergos A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud. The rider triangle is also improved with increased legroom between the seat and footpegs for enhanced rider comfort.

Engine

  • 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.
  • All-New 450cc Four-Stroke Engine The new 2024 YZ450FX's advanced four-stroke engine has been completely redesigned to be lighter, more compact, higher revving and more powerful across the entire rev range. Among the changes are new exhaust and intake port shapes, larger diameter titanium intake valves, new piston, cylinder, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. Additionally, ECU settings are tailored to suit the specific needs of cross country and enduro competition.
  • 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.
  • New Compact Lightweight Clutch The all-new clutch design replaces the coil springs of the previous model with a new 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. Premium clutch cover employs a stylish geometric design that helps minimize scratching and lends a bold look.
  • New Traction Control System An all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF.
  • New Wide-Ratio Five-Speed Transmission The YZF450FX’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 all-new 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.
  • New Yamaha Power Tuner App The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to an iOS® or Android® device, allowing owners to adjust air/fuel mixture and ignition timing, log race set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time, and more. The newest version of the app has been revised to be more user-friendly, with new features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction Control tuning, lap timer, and helpful engine and suspension tuning guides.
  • On-The-Fly Engine Mapping Selection New, 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.
