The ultimate 450 raises the bar even higher. Building on its best-in-class performance, the focus for the new 2026 YZ450F falls on maintaining the exceptional balance of power and handling while achieving a level of refinement that sets a new class standard: the easiest bike to ride faster, longer.

Updates to the renowned 450cc reversed cylinder four-stroke engine yield more linear response for enhanced control and feeling of connection.
