Yamaha engineers had to improve on a package already the best in its class for the new 2024 YZ450F. Traditional strong qualities like broad, torquey power, comfortable suspension, and predictable handling had to be improved. Still, the new model has a five-pound weight loss, more control, and better ergonomics.
The result is a smaller, lighter, and more powerful engine. It also has better handling, higher agility, and outstanding stability. Finally, the body is much sleeker and more delicate 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 aluminium 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 wholly revamped engine for 2024. 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 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 result is an assembly that is more compact, light, and robust, producing a smoother engagement and superb feel. To create a more lightweight, closed gearbox, a brand-new tri-shaft transmission arrangement stacks the transmission shafts vertically, raises the centre shaft, and forms a triangle with the crank, driving shaft, and main shaft.

2024 Yamaha YZ450F Price, Full Specs & Release Date
Yamaha’s market-leading Power Tuner App, which allows riders to customize engine performance to their preferences, has undergone major revision for 2024. it still has all of the capabilities 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 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. 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 for improved launches when the gate drops. With the Yamaha Power Tuner App, both systems are managed.
The new aluminium bilateral beam frame for the new 2024 Yamaha YZ450F is the next significant improvement. The new frame comprises more than ten separate welded aluminium components, striking the ideal mix between precise cornering performance and handling stability.
This offers the chance to precisely adjust each component’s stiffness and flex properties to guarantee success at the top level of competition. The result is a more manoeuvrable vehicle with a lighter feel, better bump absorption, and enhanced traction, giving the rider more confidence and line options as they approach turns.
Design
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 and 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 aluminium tapered handlebars, a new, compact PVC handlebar pad, new, lightweight throttle cables, wide footpegs with new, lightweight aluminium alloy brackets, a quick-adjust clutch perch, and a new chain guide. These elements work together to ensure the new 2024 Yamaha YZ450F.
