📖 Model Background

The 2023 Yamaha YZ450F is a ground-up redesign of Yamaha’s premier motocross machine, built to push the limits of factory-level performance. Featuring a newly engineered 450cc liquid-cooled DOHC 4-stroke engine with rearward-slanted cylinder design, the 2023 model sheds weight while increasing power and midrange torque. A new aluminum bilateral beam frame improves cornering precision and rider ergonomics, while the updated KYB suspension offers enhanced adjustability for competitive track performance. For the first time, the YZ450F introduces a compact smartphone-based Power Tuner app with launch control and traction tuning. Lighter, slimmer, and more powerful, the 2023 YZ450F sets a new benchmark in 450cc motocross dominance.
