New engine with greater flexibility

The intake system has been revised by changing the intake port and wall surface shapes to achieve optimum ow 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 muffer'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.
