2023 Yamaha YZ Off-Road Series

Conceived for competition and extensively developed through knowledge gained at the highest levels of professional motorsports, the 2023 lineup of Yamaha YZ Motocross and Cross Country machines offer cutting-edge performance along with a level of refinement and rideability that instills confidence in every rider. Highlights for 2023 include an all-new flagship YZ450F Motocross model, along with an all-new YZ125X and extensively updated YZ250X two-stroke Cross Country models.

2023 Yamaha YZ450F

Changes for the new YZ450F start with the engine. Completely redesigned for 2023, updates include new exhaust and intake port shapes, larger diameter titanium intake valves, a new forged aluminum piston, a new cylinder body, crankshaft, and balancer assembly, and a switch from wet sump to dry sump lubrication. The combined effect of these features is more midrange and top-end power, including a 500 rpm higher rev limit for longer over-rev, and more linear output characteristics for increased rideability and control.

Helping lay that power down to the rear wheel, an all-new cable-actuated clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight, and durable assembly which yields smoother engagement and an excellent feel. Additionally, an all-new tri-shaft transmission layout vertically stacks the transmission shafts, raising the center shaft and forming a triangle between the crank, drive shaft, and main shaft for a lighter, more compact transmission.

Providing riders with the opportunity to fine-tune engine performance to their liking, Yamaha’s industry-leading Power Tuner App has been extensively revised for 2023, retaining the full functionality of the previous version, but now even easier to use with more functionality. Engine mapping can now be made using an intuitive new slide bar. There is also a new lap timer, Traction and Launch Control tuning and bike set-up guides. Additionally, a new lightweight handlebar-mounted switch allows an on-the-fly selection of preloaded engine maps.

The all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
