WR450F
The WR450F is the fastest and most agile large capacity enduro bike ever produced by Yamaha. Using the highly advanced engine and chassis technology from the latest YZ450F motocross bike – and equipped with specially developed enduro settings – this proven winner is born to ride.

Yamaha’s engineers have taken the compact and lightweight engine from the YZ450F and developed an enduro-specific powerplant for the latest WR450F. Its ‘made-to-measure’ ECU as well as a high-compression cylinder head and a specially designed heavy-duty transmission are ready to deliver winning performance. And the best-in-class suspension and the lightweight aluminium beam frame with a finely-tuned rigidity balance give you easy manoeuvrability and accurate surface feedback.

Yamaha’s digital Power Tuner and handlebar-mounted engine mode switch put you in total control when track conditions change – and the compact multi-function display gives you all the information you need to keep ahead. Finished in a dynamic Icon Blue with in-mould graphics, the mighty WR450F is ready for any battle.

The enduro world is evolving. And to make it to the podium you need a special kind of dirt bike that combines the hard-hitting performance of a motocross machine with all-day useability and precise control. Developed from the high-tech YZ450F, the latest WR450F is built to deliver, and ready to win.

  WR450F-specfic ignition and fuel injection maps are optimized for enduro riding and racing for exceptionally smooth, controllable midrange and extended pulling power in the top-end.
• Unique Intake and Exhaust Systems
  The WR450F features an air filter that works in conjunction with the tuned intake tract length and a WR-specific muffler to boost the linear feeling of traction and drive. Not only is the WR450F muffler completely mechanical—eliminating the need to repack—it integrates a U.S. Forestry Service-compliant spark arrestor too.
• High-Capacity Radiator and Fan
  The WR450F uses a large radiator with excellent cooling capacity shared with the YZ450F motocrosser, complete with a cooling fan for consistent performance during the toughest enduro rides.
• Electric Starter System
  The WR450F features a compact electric starter system to simplify restarts on the trail and add convenience everywhere else.
• Advanced Fuel Injection
  The engine breathes through a 44mm Mikuni® throttle body fed by a high-pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding elevations and conditions.
• Robust Transmission and Clutch
  The WR450F’s wide-ratio 5-speed transmission provides the optimized gear for tight technical terrain, as well as wide open fire roads. The transmission gears use a wide surface area that is balanced against updated clutch components.

CHASSIS/SUSPENSION

• YZ450F-Derived Bilateral Beam Frame
  Yamaha’s refined aluminum frame provides high performance on technical, aggressive terrain sections and comfort for those long days in the saddle, with frame spars and engine mounts developed alongside the YZ450FX cross country racer to centralize mass for the best possible balance of bump absorption, stiffness and rider feel.
