The ultimate 450 elevates performance to new heights. Building on its best-in-class capabilities, the focus for the new 2026 YZ450F is on maintaining an exceptional balance of power and handling while achieving a level of refinement that sets a new standard in its class: it’s now the easiest bike to ride faster and for longer periods.
A new frame design and reworked suspension enhance confidence and cornering performance. Updates to the renowned 450cc reversed cylinder four-stroke engine provide a more linear response for improved control and a greater sense of connection. Additionally, the new hydraulic clutch and the industry-leading Yamaha Power Tuner app ensure that the best just got even better!
Engine performance has improved with a redesigned intake port that enhances the tumble effect in the combustion chamber, leading to more efficient combustion. This results in a more linear response, providing better control and connection between the throttle and rear wheel.
A new frame design for 2026 balances rigidity and flex. A revised inner and outer structure with a thinner front downtube enhances ride stability and front-end feel for better cornering performance.
A new hydraulic clutch enhances rider comfort with smooth, consistent engagement and less effort, eliminating on-track adjustments. Its redesigned inner hub lubricates a larger area for improved performance and longevity.
Yamaha's Power Tuner App lets users adjust engine performance, monitor data, and record race logs. It features easy tuning options, lap timing, and guides for tuning, all available for free.
The 2026 YZ450F introduces an industry-first ECU lock function designed to deter theft. This feature allows owners to prevent unauthorized engine start-up through a password-protected lock, which can be accessed via the Yamaha Power Tuner app.
Careful computer-aided design of each wheel’s cross-sectional profile reduces weight without sacrificing durability. The rear wheel of the YZ450F features a three-cross spoke pattern for improved impact absorption and rider feel.
A new shock and fork settings improve damping feel and reduce bump response, allowing riders to push harder longer. It includes a hand-operated low-speed compression clicker for easier adjustments.
The optimized intake path draws air from beneath the side covers and seat, resulting in a lighter, slimmer, and more compact shroud area. The airbox cover is positioned low and is narrow, surrounded by the streamlined radiator shrouds.
The bike comes equipped with a 270-mm front brake rotor and a Nissin calliper, ensuring optimal braking performance. The rear brake has also been improved by reducing the rigidity of the brake hose, allowing for a wider range of control at the pedal.
Tri-shaft transmission layout vertically stacks the transmission shafts, raising the centre shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission.
Updated styling includes a slimmer, more compact front number plate, new two-piece side covers, sharper rear fender, and new YZ graphics, and a new honeycomb-pattern seat cover material maintains ease in rider sliding forward while improving hold from sliding rearward during acceleration.
