This championship-proven 450cc four-stroke motocross bike, available in Team Yamaha Blue or the limited 70th Anniversary Edition with iconic white/red livery, features an all-new frame, updated suspension, and engine refinements for unmatched rider confidence on tracks, ruts, and jumps.

POWER & PERFORMANCE
Powered by a 450cc liquid-cooled DOHC four-stroke single-cylinder engine with reversed cylinder head layout, forged aluminum piston, and 39mm titanium valves, the YZ450F delivers broad torque and high-revving power exceeding 60 hp. The tri-shaft 5-speed transmission with disc spring clutch ensures smooth shifts and durability, while dry sump lubrication and lightened crank assembly optimize efficiency. Updated airbox with resonator reduces noise for compliant racing without sacrificing performance.

DESIGN & CHASSIS
Engineered for supremacy with a bilateral asymmetrical aluminum frame weighing 247 lbs dry, 12.8 inches of ground clearance, and a 58.3-inch wheelbase for balanced agility. The 1.9-gallon fuel tank supports full motos, complemented by a 38.6-inch seat height and slim, flat bodywork for fluid movement. New styling includes a compact front number plate, two-piece side covers, and slimmer rear fender with embedded graphics.

SUSPENSION & HANDLING
KYB Speed Sensitive System 49mm inverted fork front delivers 12.2 inches of travel with fully adjustable damping for superior bump absorption. The KYB rear shock provides 12.4 inches of travel with new hand-operated low-speed compression clicker for enhanced feel. Rack-and-pinion steering and revised frame geometry improve front-end feedback, paired with 270mm front disc brake and 245mm rear disc for precise stopping power. Dunlop Geomax MX33 tires (80/100-21 front, 120/80-19 rear) on Excel rims with 3-cross rear lacing ensure grip and impact resistance.

YZ450F FEATURES
The 2026 YZ450F includes Yamaha Power Tuner App with Wi-Fi connectivity for real-time EFI mapping, three-level traction control, launch control, and lap timer. New ECU lock via app PIN prevents theft, while the handlebar map switch with blue light offers three engine maps. Additional upgrades: Nissin hydraulic clutch, wide footpegs, quick-adjust clutch perch, gold drive chain, and one-way gripper seat cover to prevent sliding. 51-tooth rear sprocket maintains gearing with sound-compliant exhaust.
