New 2023 Yamaha YZ450F & Monster Energy® Yamaha Racing Edition YZ450F:
For the new 2023 YZ450F, Yamaha engineers were tasked with improving on an already class-leading package. Traditional strong points of broad, torquey power, plush suspension and predictable handling had to be enhanced, but with a distinctly rider-centric focus for the new model with a five-pound weight reduction, increased control and improved ergonomics. The end result is a lighter, more compact engine that pumps out even more power, improved handling with greater agility while still maintaining excellent stability, and a significantly lighter, slimmer body with enhanced ergonomics for greater control.

Changes for the new YZ450F start with the engine. Completely redesigned for 2023, updates include new exhaust and intake port shapes, larger diameter titanium intake valves, new forged aluminum piston, new cylinder body, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. The combined effect of these features is more midrange and top-end power, including a 500 rpm higher rev limit for longer over-rev, and more linear output characteristics for increased rideability and control.

Helping lay that power down to the rear wheel, an all-new cable-actuated 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 smoother engagement and excellent feel. Additionally, an 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.

Providing riders with the opportunity to fine-tune engine performance to their liking, Yamaha’s industry-leading Power Tuner App has been extensively revised for 2023, retaining the full functionality of the previous version, but now even 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 and Launch Control tuning, and bike set-up guides. Additionally, a new lightweight handlebar-mounted switch allows on-the-fly selection of preloaded engine maps.

The 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. The updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.

The next major update to the new 2023 YZ450F involves the completely redesigned aluminum bilateral beam frame.
Striking the perfect balance of precise cornering performance and handling stability, the new frame consists of more than 10 different aluminum components welded together. This provides the opportunity to carefully tune rigidity and flex characteristics of each component to ensure competition-level performance. 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.

Improving on the YZ450F’s already category-defining suspension performance, new internal suspension valving works in combination with the new frame and body to provide exceptional bump absorption, increased traction and better cornering performance. High-spec fully adjustable Speed Sensitive System KYB® coil spring-type forks now feature a new hand-operated compression damping adjuster for simple, toolless adjustments, and the linkage-type rear suspension features a KYB® shock with damping characteristics to match the new chassis.

Finally, a new slimmer, flatter and more compact body design lends a much lighter, more precise riding feel. A completely redesigned air intake pathway, airbox and filter allow for a narrower fuel tank, significantly slimmer front shrouds and a lower airbox cover. Additionally, more seamless, rounded features including seat edges and side covers further ease rider movement for improved control. 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.

Other top-spec details and convenient features include a push-button electric starter system with high-capacity ultra-light lithium-ion battery, 1-1/8-inch aluminum tapered handlebars, new compact PVC handlebar pad, new lightweight throttle cables, wide footpegs with new lightweight aluminum alloy brackets, a quick-adjust clutch perch and new chain guide all combine to ensure the new 2023 YZ450F continues to be the most complete, most well-balanced, most capable bike in the 450 class.
