The journey of progress isn’t always clear in the present moment. There are often wrong turns and misfires along the path forward. Yet, upon reflection, a point of no return in technological advancement becomes apparent.
The 2024 lineup of 450 motocross bikes unmistakably signifies that there’s no turning back. While only two of the seven bikes have undergone significant changes this year, it’s evident that we have entered a new era of electronic development.
All manufacturers now incorporate some form of electronic adjustment to customize the personalities of their products, a trend that will likely grow in significance as we are propelled forward by the irresistible force of progress.
