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.
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.
