The class benchmark. Yamaha took the championship winning YZ450F and made it even better with highly refined power and handling characteristics for a level of feel and control that unlocks a racers full potential.

Features may include:

Powerful 450cc Four-Stroke Engine

Featuring a reversed cylinder head layout, forged aluminum piston, 39 mm titanium valves, lightened crank assembly and dry sump lubrication, the 2026 YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range

Advanced Aluminum Bilateral Beam Frame

The precisely tuned aluminum bilateral beam frame provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.

Class-Leading Suspension

The YZ450F's high-spec fully adjustable Speed Sensitive System KYB coil spring-type fork is recognized as the gold standard in the 450 class, providing exceptional feel and bump absorption. A new high performance KYB shock with new hand-operated low-speed compression clicker further enhances damping feel with less bump reaction, providing the confidence to ride harder for longer.

Slim, Compact Ergonomics

The YZ450F's slim, flat, compact body eases rider movement for improved control. The rider triangle is also optimized for increased legroom between the seat and foot pegs, with a carefully considered handlebar position for a more natural posture and enhanced rider comfort. Updated styling cues for 2026 now include a more compact front number plate, new two-piece side covers, sharper rear fender and new YZ graphics.

The 2027 Yamaha YZ450F stands out with a high-performance DOHC 4-stroke engine featuring 4 titanium valves and a liquid-cooled design that emphasizes precise power delivery and quick throttle response. With a 450cc displacement and Mikuni fuel injection operating through a 44mm intake, this motorcycle is built to deliver strong mid-range torque and confident top-end pull. The short, responsive 5-speed transmission with a multiplate wet clutch keeps you in the power band, while a chain final drive ensures efficient power transfer to the rear wheel.

On the chassis, the Yamaha YZ450F combines advanced suspension and a compact profile to support aggressive riding styles. The front suspension is a KYB spring-type fork with speed-sensitive damping and fully adjustable 12.2-in travel, complemented by a KYB single rear shock with 12.4-in travel for balanced handling on rough terrain. Front and rear brakes are sized for performance, with precise control and consistent stopping power, while Dunlop Geomax MX33F/MX33 tires provide confident grip across varying traction conditions. The lightweight frame and tuned geometry work together with a wheelbase of 4.84 ft and a seat height of 3.17 ft to deliver nimble, responsive handling.

Designed for serious off-road riding, the Yamaha YZ450F leverages a compact 1.6 gallon fuel tank and a total weight of 243 pounds (wet), ensuring a ready-to-roost package that remains manageable on tight trails. Induction uses a Mikuni fuel injection system for reliable throttle response in all conditions, and the rake of 27.5 degrees helps with steering precision at speed.
