The 2024 Yamaha YZ450FX is a championship-winning off-road competition dirt bike engineered for cross-country racing, enduro events, and aggressive trail riding. Powered by a 450cc liquid-cooled DOHC four-stroke single-cylinder engine with Yamaha's rearward-slanted cylinder design, it delivers exceptional horsepower, strong low-end torque, and instant throttle response for maximum performance across challenging terrain. The advanced Electronic Fuel Injection (EFI) system provides precise fuel delivery and consistent power in a wide range of riding conditions.
The engine is paired with a 5-speed wide-ratio manual transmission, optimized for off-road competition by providing smooth power delivery, excellent hill-climbing capability, and comfortable high-speed trail performance. Yamaha's lightweight aluminum bilateral beam frame delivers exceptional rigidity, precise cornering, and excellent rider feedback while maintaining outstanding agility over technical terrain.
Built specifically for cross-country racing, the YZ450FX features KYB® Speed-Sensitive System (SSS) fully adjustable front forks and a fully adjustable KYB® rear shock, offering industry-leading suspension performance over rocks, roots, whoops, and rough trails. Yamaha's Power Tuner App allows riders to customize engine mapping, traction control, and launch control directly from a smartphone, giving racers the ability to fine-tune performance for changing terrain and conditions.
