2026 YZ450F

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.
