2027 Big Bore MX Weapon

Yamaha’s class-dominating YZ450F sets the bar for motocross performance, delivering highly refined power and handling characteristics to level up your game.


The advanced DOHC four-stroke engine is light and compact with world-renowned and incredibly broad pulling power across the entire rev range, while the precisely tuned aluminium bilateral beam frame balances strength and flex to optimise stability and cornering performance, delivering better handling with lighter feel, more agility, and increased traction allowing the rider to enter corners with greater confidence and more line choices.
