Featuring a powerful engine producing strong, linear torque – and equipped with a compact aluminium chassis and slimline bodywork developed from the YZ450F – the agile WR450F gives you race-winning performance with class-leading versatility and legendary reliability.
Its wide power delivery can be quickly and easily tuned to suit different conditions via onboard WiFi using the Power Tuner app – and with its responsive handling and industry-leading suspension systems, the WR450F has got to be one of the smartest and most complete enduro bikes in any environment.
You want high fuel capacity as well as slim bodywork. So Yamaha’s designers placed the fuel tank low in the chassis to improve mass centralisation – and installed a compact fuel pump to save space. This way you get a 7.9-litre tank for maximum riding time between refills, together with ergonomic bodywork that enables easy manoeuvrability with optimum riding comfort.
Get on the WR450F and you’ll immediately appreciate this bike’s sleek layout. The compact frame and close-fitted radiators have enabled Yamaha’s designers to fit slim bodywork that makes this 450 look and feel more like a 250. And to reinforce the feelings of agility and lightness, the headlight is mounted close in to the forks, underlining the bike’s total design.
The bilateral beam frame is both slim and light, making it feel very agile through twisty, rocky and technical terrain. The aluminium frame is constructed with optimised levels of rigidity, giving light handling together with accurate surface feedback – enabling you to maintain high levels of control over bumps and on loose or slippery surfaces.
Featuring internals with long high-rate springs, the industry-leading Air-Oil-Separate front forks provide stable damping characteristics over all types of terrain. For consistent rear damping and increased stability, the rear shock is fitted with a light spring and a large capacity reservoir.
The tough enduro-specification clutch uses special heat-resistant frictions plates that can withstand harsh operating conditions – and there’s a light pull at the lever, giving you better feel for improved controllability. For optimum performance in low- and high-speed situations, the WR450F is equipped with a 5-speed wide-ratio transmission.
Whether you’re sitting down or standing up, the seat’s slim design makes it easy to shift your body weight. As well as being narrow in the front section, the middle and rear sections of the seat are also low, enabling you to move backwards or forwards more easily for a high degree of control when cornering, accelerating or braking.
The WR450F features a large and light plastic resin skid plate that protects the frame, engine, hoses and water pump – and also prevents mud and stones from accumulating in any cavities around the crankcases. And the lightweight speed sensor makes removing and refitting the front wheel much easier and quicker.
As well as its high performance engine and lightweight frame, the WR450F features tough radiators and stylish shrouds. The front-mounted air intake funnel and free flow filter contribute towards more linear performance with stronger traction – and for quick and simple maintenance, the airbox can be opened manually without the need for any tools.
To help keep your WR450F looking good the bodywork is fitted with tough wear-resistant graphics. By being moulded within the actual plastic bodywork, these graphics can better withstand the constant onslaught of mud, dirt and pressure washers that every dirt bike experiences on a regular basis.
Yamaha’s Power Tuner app allows you to adapt your WR450F’s engine character and performance to suit different riding conditions – and you can also access engine running data and record race log information. Using your smartphone with the Communication Control Unit (CCU), it’s easy to adjust the air-fuel mixture and ignition timing to achieve optimum performance.
When you’re riding in the dirt you’ve got to be prepared for constantly changing surface conditions as well as extreme weather. With the switchable engine modes you can select the appropriate power delivery mode using the handlebar mounted switch, enabling you to take control on everything from slow, technical terrain through to high-speed tracks.
The 450cc engine’s special combination of a front-facing inlet together with a high compression piston, racing camshafts and a 4-valve head deliver strong, linear torque for race-winning performance – while the enduro-specific fuel injection settings and ignition mapping give you improved control in technical terrain.
