First Looks: 2023 Yamaha YZ450F Price, Full Specs & Release Date

Yamaha YZ450F

Yamaha engineers had to improve on a package that was already the best in its class for the new 2023 YZ450F. Traditional strong qualities like broad, torquey power, comfortable suspension, and predictable handling had to be improved, but for the new model with a five-pound weight loss, more control, and better ergonomics. The end result is an engine that is smaller, lighter, and produces even more power. It also has better handling, higher agility, and outstanding stability. Finally, the body is much sleeker, lighter, and has improved ergonomics for greater control.

Starting with the engine, the new YZ450F has changed. New exhaust and intake port designs, larger diameter titanium intake valves, a new forged aluminum piston, a new cylinder body, crankshaft, and balancer assembly, as well as a transition from the wet sump to dry sump lubrication, are just a few of the modifications made to the completely revamped engine for 2023. With the addition of a 500 rpm higher rev limit for longer over-revs and more linear output characteristics for improved ride-ability and control, these features together produce more midrange and top-end power.

A brand-new cable-actuated clutch design combines the primary gear and basket into a single steel piece, replaces the coil springs from the previous model with new disc springs, and helps transfer that power to the rear wheel. The end result is an assembly that is more compact, light, and robust and produces a smoother engagement and superb feel. In order to create a lighter, more compact gearbox, a brand-new tri-shaft transmission arrangement stacks the transmission shafts vertically, raises the center shaft, and forms a triangle with the crank, driving shaft, and the main shaft.

Yamaha’s market-leading Power Tuner App, which offers riders the chance to customize engine performance to their preferences, has undergone major revision for 2023; it still has all of the capability of the previous edition but is now much simpler to use and has more features. A simple new slide bar can now be used to map engines. A new lap timer, Traction and Launch Control settings, and bike set-up instructions are now included. Additionally, a brand-new, lightweight switch positioned on the handlebars enables instantaneous adjustment of preloaded engine maps.

The brand-new Traction Control System adjusts the engine to ensure ideal rear wheel traction by communicating wheel slip to the ECU. There are three settings available: HIGH, LOW, or OFF. For improved launches when the gate drops, the revised Launch Control System now has an rpm limiter that can be changed in 500-rpm steps between 6,000 and 11,000 rpm. With the Yamaha Power Tuner App, both systems are managed.

The entirely new aluminum bilateral beam frame for the new 2023 Yamaha YZ450F is the next significant improvement. The new frame is made of more than 10 separate welded aluminum components, striking the ideal mix between precise cornering performance and handling stability. This offers the chance to precisely adjust the stiffness and flex properties of each component to guarantee success at the top level of competition. The end result is a more maneuverable vehicle with a lighter feel, better bump absorption, and enhanced traction, giving the rider more confidence and line options as they approach turns.

The 2023 Yamaha YZ450F’s already category-defining handling performance is enhanced by new internal suspension valving, which functions in tandem with the revised frame and body to offer superior bump absorption, more grip, and improved cornering performance. superior completely adjustable the speed-sensitive system for easy, tool-free changes, KYB® coil spring-type forks now have a new hand-operated compression damping adjuster, and the linkage-type rear suspension now has a KYB® shock with damping characteristics that match the new chassis.

Finally, a new body design that is thinner, flatter, and more compact makes riding feel lighter and more accurate. A narrower fuel tank, much slimmer front shrouds, and a lower airbox cover are made possible by a newly reworked air intake pathway, airbox, and filter. Further easing rider movement for better control is more smooth, rounded features like seat edges and side coverings. Increased legroom between the seat and footpegs, as well as a new handlebar position that promotes a more natural posture and greater rider comfort, all contribute to an improved rider triangle.

Other high-end components and practical features include a push-button electric starter system with a high-capacity, ultra-light lithium-ion battery, 1-1/8-inch aluminum tapered handlebars, a new, compact PVC handlebar pad, new, lightweight throttle cables, wide footpegs with new, lightweight aluminum alloy brackets, a quick-adjust clutch perch, and a new chain guide. These elements work together to ensure the new 2023 Yamaha YZ450F.
