For winners, by winners: the 2026 YZ450F
The new YZ450F features a new engine, with the intake system redesigned for greater ease of use with more linear throttle response and improved control in the low-to mid-speed range. Torque characteristics have also been improved for better feel.
The exhaust has been made quieter, and the muffler’s attachment angle was lowered slightly to create more space to allow easier pick up at the rear fender. The 2026 YZ450F also features a new hydraulic clutch, which eliminates the need for adjustments during racing, keeping the meshing point constant during continued riding.
The YZ450F’s frame has been further improved to achieve even greater usability, comfort and feel. To match it characteristics, the front suspension setting has been modified, further improving the feel and stability, and reducing fatigue. For the rear, a new rear suspension has been jointly developed with KYB, providing smoother transition of the damping force from the low-to high-speed range.
When the 2026 YZ450F is parked between the races, an ECU lock function enables the rider to lock the bike on the Power Tuner App. The YZ450F also delivers when it comes to looks. The new bodywork has been styled to accentuating its light and compact stance, while a new seat with anti-slide surface provides better control.
Tying the model even firmer to Yamaha’s past, present and future racing success is the YZ450F 70th Anniversary Edition, featuring a stunning white and red livery inspired by the iconic YZM400F.
