The 2026 Yamaha YZ450FX is built for riders who want uncompromising cross-country performance, race-winning power, and championship-level off-road capability.

Developed from Yamaha’s legendary YZ450F motocross platform, the YZ450FX combines aggressive power delivery, lightweight handling, and off-road-focused tuning to dominate everything from tight technical terrain to high-speed cross-country racing.

Powered by a high-performance 450cc liquid-cooled 4-stroke engine, the YZ450FX delivers explosive acceleration, massive torque, and strong top-end performance while maintaining the smooth controllable power delivery needed for demanding off-road conditions.

The lightweight bilateral beam chassis, premium KYB suspension package, and race-developed ergonomics provide exceptional stability, rider feedback, and confidence across rough terrain, whoops, ruts, fast trails, and technical enduro sections.

Built specifically for off-road competition, the YZ450FX features enduro-focused ECU settings, an 18-inch rear wheel, larger fuel capacity, electric start, and Yamaha’s advanced Power Tuner app, allowing riders to customise engine mapping and performance settings directly from their smartphone.
