2023 Yamaha WR450F

ENGINE

• Rearward-Slanted Cylinder Design
  The WR450F’s distinct rearward-slanted cylinder design - complete with rear exhaust and forward-mounted intake system - features a cylinder head that works with the frame geometry for optimised weight distribution. All the updates found in the race-focused YZ450F are specified including a light, compact cylinder head, aggressive cam profiles, high-compression box bridge piston design with DLC-coated piston pin and more.

  Engine Tuned for Enduro
  WR450F-specfic ignition and fuel injection maps are optimized for enduro riding and racing featuring longer and stronger pulling power with increased controllability.

  Unique Intake and Exhaust Systems
  The WR450F features a two-piece 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. The WR450F muffler is completely mechanical, eliminating the need to repack.

  High-Capacity Radiator
  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 44 mm 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 clutch system has a light pull with specific heat-resistant friction plates for tough enduro competition.

CHASSIS / SUSPENSION

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

Compact Body and Seat Design
The WR450F features stylish bodywork from tip to tail, including a large 7.9-litre, mass-centralized fuel tank. The body design is narrow for more comfortable knee grip and control feeling while the seat gives the rider additional room to move aboard the machine. Even the rear fender is designed for added rigidity to make moving the machine easier.

Class-Leading Suspension
The WR450F’s industry-leading, fully adjustable KYB coil spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption. Settings are specifically tuned for enduro and to match the new frame.

Enduro Wheels and Tires
The WR450F features an 18-inch rear wheel to help prevent pinch flats and provide additional comfort across rough terrain.
