The reigning US Motocross and Supercross champ now raises the bar even higher. Building on its best-in-class power delivery and suspension performance, the all-new 2023 YZ450F boasts even more power, better handling, less weight, a new more narrow body with improved ergonomics and next-generation Power Tuner app — all while maintaining its renowned ease-of-use that makes fast riders even faster.


Our engineers have taken that winning package and made it lighter, more compact and boosted power across the entire rev range with and all-new 450cc engine. To further cement the YZ450F’s position at the top of the tree, new styling is specified with a slim shroud, shorter front mudguard, extended front fork protectors and new flexible riding position.


Finished in Team Yamaha Blue duo-tone colours with new in-mould graphics, the YZ450F is ready to tune in to victory.
