Yamaha's class-dominating YZ450F sets the bar for motocross performance, delivering highly refined power and handling characteristics to level up your game.

Features may include:

The 2027 YZ450F's advanced DOHC four-stroke engine is light and compact with world-renowned and incredibly broad pulling power across the entire rev range, thanks to its reversed cylinder head layout, forged aluminum piston, 39 mm titanium valves, lightened crank assembly and dry sump lubrication.

The precisely tuned aluminum bilateral beam frame balances strength and flex to optimize stability and cornering performance and deliver better handling with lighter feel, more agility, and increased traction allowing the rider to enter corners with greater confidence and more line choices.

An all-new rear braking system provides linear stopping power with improved braking force and controllability in a smaller, lighter package. The size of the rear brake caliper and master cylinder pistons have been reduced, as well as the diameter of the rear brake disc (220mm). The brake hose material and disc rotor bolts have also been revised resulting in 180g of weight savings.

Ride harder for longer thanks to the YZ450F's high-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork, known as the gold standard in the 450 class with exceptional feel and bump absorption, combined with the high performance KYB® shock with hand-operated low-speed compression clicker that deliver excellent damping feel with less bump reaction.

Yamaha's free downloadable Power Tuner App provides unmatched smartphone tuneability by allowing owners to adjust air/fuel mixture and ignition timing to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more. Features include an intuitive “Simple Tuning” slide bar for quick engine mapping adjustments, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides.

The YZ450F's slim, flat, compact body makes it easy for riders to move around improving control. The optimized rider triangle provides ample legroom between the seat and foot pegs, with a carefully considered handlebar position that allows for a natural posture and increased comfort. Styling includes a compact front number plate, two-piece side covers, sharp rear fender and YZ graphics.
