Yamaha YZ 450F

Whatever level you race, the YZ450F has the firepower to see you win. The new engine delivers the same race-winning power as before, but now with greater ease of use in low to mid-range and greater feeling of power at the top of the range. The new exhaust system meets the latest noise regulations, and the new hydraulic clutch gives better feel for the meshing point and lighter operation.

For winners, by winners.
When the starting point is already so high, making improvements becomes harder. The YZ450F already had a highly praised chassis setup, but the new model introduces a new frame and updates to suspension to ensure a smoother ride, greater feel for traction and a more planted feel over varied terrain, while maintaining the excellent stability and cornering performance. The seat cover features new material to stop the rider sliding back on acceleration, helping you maintain control and keep your focus on winning.

Winning races takes more than just old school tuning – the YZ450F is at the forefront of technology to give you the best advantage on track. The easy-to-use Power Tuner app enables you to make quick trackside adjustments to the engine character and traction control settings to match the conditions, and keep you ahead of the pack. The new ECU lock makes it easy to protect your bike when you're not riding by preventing the engine from starting until you enter your password in your phone, keeping your pride and joy safe.

Features

New engine with greater flexibility
The intake system has been revised by changing the intake port and wall surface shapes to achieve optimum flow with a smaller cross-section and create a vertical vortex in the combustion chamber. This increases combustion efficiency in the low- to mid-rpm range, while maintaining the power higher in the range.

New frame for better control and comfort
The new frame features redesigned inner structure and thickness of the downtubes as well as bilateral asymmetric engine mounts to adjust the frame's torsional behaviour. This reduces rigidity in response to upward thrusts, while maintaining the same levels of longitudinal, lateral and tortional rigidity. This achieves calmer and highly stable front-end feeling, improved chassis balance and contact feeling, better stability in ruts and braking pumps, and less weight transfer.

Better feel with hydraulic clutch
New hydraulic clutch replaces the previous wire-operated one to offer a more stable performance and keep the meshing point constant during continued riding. It provides better feel for the meshing point, smoother clutch feathering action and lighter operation.

Keeping the noise down
The 2026 YZ450F exhaust has been made quieter with a centrally positioned resonator and tuning changes, while the muffler's attachment angle has been lowered slightly to create more space to allow easier pick up at the rear fender. The air cleaner now features an added resonator and duct to reduce induction noise.

Smoother ride and better feel
The new YZ450F introduces a new frame with optimised rigidity to ensure a smoother ride, improved comfort and a more planted feel when riding over bumps and landing jumps. The bike still maintains the excellent stability and cornering performance it is famous for.

Revised suspension settings
Updates to suspension achieve greater feel for traction as well as stability. The rear shock has been newly developed with KYB with a smoother transition from slow- to high-speed damping. There is now also a hand-operated compression damping adjuster.

New styling
The YZ450F has been styled to accentuate its light and compact looks. The slim and low race number plate adds to the agile and light looks. The newly-adopted two-piece side covers have a two-tone colour emphasising the YZ series' trademark horizontal lines. The rear mudguard has a solid look, and it’s easier to grasp when manoeuvring the machine. The YZ logos on the shroud in an inverted type, and the “speed block” graphics mark the bike as part of the race-winning family.

ECU lock anti-theft device
An ECU lock function enables the rider to lock the bike via a smartphone, and the engine can’t be started again until the password is correctly entered on the phone. The function provides a great anti-theft system for a bike with no physical key.

New anti-slide seat
The new material chosen for the seat features a honeycomb pattern with a depth and grain designed to reduce the potential of the rider sliding back on the seat during acceleration. The new pattern also makes it easier to move forward in the seat.

Power Tuner App for easy tuning
Power Tuner features a 'Simple Tuning' function that enables you to easily select any engine setting from 'Smooth' to 'Aggressive'. A lap timer function allows you to monitor improvements in your performance, and an FAQ section explains the most effective way to select the best engine and suspension tuning for any given situation.
