2026 Yamaha YFZ450R SE

TRACK-TAMING BEAUTY

This Special Edition features track-worthy performance, added Yamaha Genuine accessories and a unique color and graphic scheme that looks fast just standing still.

Features may include:

ENGINE

High-tech, quick-revving, 449cc fuel-injected engine provides championship-winning power characteristics.

Five-valve cylinder head and titanium valve technology delivers abundant mid-range and top-end power.

Revised camshafts maximize engine's impressive power output from off the line all the way up to the top-end.

High compression ratio further improves overall engine performance.

Yamaha Fuel Injection (YFI) offers precise fuel delivery and smooth power delivery.

Big 42mm Mikuni® throttle body and 12-hole injector provide exceptional fuel atomization for maximum power.

CHASSIS/SUSPENSION

The YFZ450R SE's motocross-ready chassis is built for competition straight out of the box.

Professional-caliber frame is designed from lightweight, weldless aluminum with a tension-steel bottom frame.

Steel frame member under the engine provides strength and lets the engine sit lower for enhanced mass centralization.

The aluminum frame section is bolted together, rather than welded, for maximum durability.

Narrow A-arm mounting points increase A-arm length and reduce changes in camber as the suspension travels.

Fully adjustable front KYB® shocks are longer for increased stroke, superb bump absorption and excellent bottoming resistance.

ADDITIONAL FEATURES

Aggressive styling gives the YFZ450R SE the looks to match its competition-dominating performance.

Added SE features include a dealer-installed GYTR® front grab bar and a unique graphics package.

The large-diameter tapered handlebar reduces vibration and is mounted on four-way clamps for exceptional adjustability.

Rider to choose between standard handlebar setting, 10mm forward, 20mm forward or 10mm backward.

The throttle lever requires low effort for less fatigue during long motos.

The generous 2.6-inch-wide foot pegs add confidence while getting up on the pegs.
