PURE OFF-ROAD PERFECTION.

Packed with "out-of-the-box" off-road features -- perfect for enduros and off-road thrill seekers.

Features may include:
  • Engine
Enduro-Tuned YZ450F Power

YZ450F-style 449cc liquid-cooled DOHC four-stroke with four titanium valves and forward intake and rearward exhaust shares the YZ450F’s piston and cam profiles, with WR450F-specific silencer and ECU tuning built for enduro racing.

Advanced Fuel Injection

Fuel injection system delivers precise throttle response and smooth power delivery at all altitudes and temperatures, featuring a high- performance 44mm throttle body. The air filter is easily accessed without tools and is positioned high in front of the bike, away from dirt roost from the rear tire and further away from water and mud.

Compact Engine Layout

Dry-sump lubrication system carries the oil reservoir inside the engine cases, for excellent mass centralization and no exposed oil lines that can be damaged.

  • Chassis/Suspension
Bilateral Beam Aluminum Frame

YZ450F-based frame offers a compact size while optimizing mass centralization. With its extensively tested assembly of aluminum forgings and extrusions complete with model-specific engine mounts, the WR450F frame retains legendary Yamaha handling and response.

Compact and Lightweight Chassis

Compact YZ450F-based chassis provides a lightweight feeling with advanced suspension systems for plush and responsive performance for the most demanding rider.

Legendary KYB® YZ450F Front Fork

Industry leading, fully adjustable YZ450F-based KYB® spring-type fork with speed-sensitive damping and Kashima Coat™ has been specifically tested and tuned for enduro racing and delivers precise, fade-free handling. Fork protectors provide excellent tube protection.

  • Comfort
Distance-Ready WR Ergonomics

YZ-family derived bodywork and seat look and feel excellent on long rides, with ultra-wide footpegs, four-position, rubber-mounted adjustable bar clamps and a tapered aluminum handlebar for great on- the-trail comfort.
