2025 Yamaha YZ450FX

The premier XC racer built to compete straight out of the box, the YZ450FX takes off-road performance to the next level. Featuring even more power, better handling, and less weight with improved ergonomics and next-generation Power Tuner app, the YZ450FX is ready to make fast riders even faster!

Features may include:

• HIGH PERFORMANCE 450CC ENGINE

Lighter, more compact with increased power across the entire rev range, the powerful 450cc engine maintains the previous YZF450FX model's exceptional pulling power and renowned ease-of-use, with ECU settings tailored to enhance low-end tractability and a 500 rpm higher rev limit for even more top-end power.

• ADVANCED ALUMINUM BILATREAL BEAM FRAME

The advanced aluminum bilateral beam frame with YZ450FX-specific engine mounts provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to tackle tight, technical trail sections with greater confidence.

• INDUSTRY LEADING YAMAHA POWER TUNER APP

Like having factory team support in your pocket, Yamaha's groundbreaking next-generation Power Tuner App is even more user-friendly with an intuitive “Simple Tuning” slide bar for quick engine mapping, three-level Traction Control, a lap timer, and helpful engine and suspension tuning guides. Best of all, it's free-of-charge.

• The Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction

• A compact, lightweight, and durable clutch air intake
