Yamaha has unveiled two updated models: the YZ450F and YZ250F. Both motorcycles have undergone exhaust redesigns to comply with the 2025 noise regulations established by the FIM. The YZ250F now offers enhanced power characteristics, resulting in smoother and more controllable lower-end response and a linear mid-range.
The YZ450F has undergone noteworthy improvements, including increased clutch cooling efficiency. The number of oil-feeding holes in the clutch plates has tripled from six to 18. The manufacturer claims the riding experience has also been refined, with a redesigned seat featuring a single layer of surface material and a seamless design to eliminate joins and welds. Furthermore, new aluminium footpeg brackets have been introduced to provide a more secure hold on the chassis for enhanced control.
A newly designed handlebar switch box has been implemented to minimise accidental presses when wearing gloves. The 2025 YZ450F also features a new throttle grip to reduce pressure on the rider’s thumb and optimised fuelling and ignition timing to improve control and throttle connection. The updated look is complemented with new graphics and redesigned suspension at both ends.
RRP’s are £9500 for the YZ450F and £9000 for the YZ250F. Full specs can be found at www.yamaha-motor.eu/gb/en/news/2025-off-road-competition-range.
