Innovative security features installed on the YZ450FX and YZ250FX

The four-stroke YZ450FX and YZ250FX are the first commercially available off-road competition models to be equipped with an ECU lock function to help prevent theft. This function works in conjunction with the dedicated Power Tuner app, and prevents the engine from starting unless a password is entered.

In addition to the engine tuning function using the “Power Tuner” that has been installed previously, a new security function has now been added, making this a groundbreaking system that can significantly reduce the risk of theft for racing bikes.

The traction control function of the YZ450FX has also evolved.

The Power Tuner app for the YZ450FX has been upgraded, and the traction control system’s intervention level has been changed from the previous three levels to four levels (including OFF). This change allows riders to make more detailed settings to suit a variety of conditions.

Styling that further evolves the horizontally-based design

The 2026 model further evolves the existing horizontally-oriented design, emphasizing a sense of speed and stability while retaining the distinctive Yamaha design style that exudes a vibrant vitality.

The large logo on the shroud expresses strength.

A large logo is placed on the shroud, expressing strength, individuality, and presence. This design element creates a powerful look that sets it apart from other models.

Superiority in off-road competitions

The ECU lock function allows for more secure bike management at competition venues. By reducing the risk of theft, riders can concentrate more on the competition.

In addition, the refinement of the traction control system allows for a wider range of settings to be adjusted to suit changing road conditions, which is expected to improve competitiveness in competitions.
