2027 Yamaha WR450F: THE ULTIMATE ENDURO MACHINE.
Introducing the new 2027 Yamaha WR450F…
Designed to tackle the trail and top the podium, the WR450F is a light, slim, sharp and powerful off-road package for fun rides and fast races.
The WR450F features a host of engine revisions designed specifically for enduro riding to produce predictable, controllable power while optimising low-end grunt, without losing its strong linear performance. The improved engine control and 5-speed wide ratio transmission deliver increased performance and traction over a wide speed range, while the Power Tuner app makes it easier to select the right mapping for total control in widely varying track and weather conditions.
Equipped with a lightweight aluminium chassis, the WR450F feels more compact and agile than ever. The frame has been redesigned to enhance response and controllability, with a thickened upper section, narrower bottom section and asymmetric engine mounts specifically for enduro performance. The latest KYB suspension works in harmony with the new chassis design, with an increased spring rate and oil level giving you better feeling, with precise damping and minimum weight transfer.

2027 Yamaha WR450F Totalmotorcycle.com Features and Benefits
Class leading YZ450F-based engine
Sometimes, there’s no substitute for power. The next generation 450cc 4-stroke reverse-head engine is the strongest and most advanced design ever used on a Yamaha enduro bike. Its enduro specific camshaft timing purposefully suppresses low-rpm torque to optimise it for enduro riding while delivering smoother power characteristics and reducing the tendency for engine stalls giving you extra confidence on the trails.
Meeting the latest noise regulations
The WR450F exhaust utilises a centrally positioned resonator, while the air filter also houses a resonator and duct to reduce induction noise to meet the latest sound regulations. Its front facing intake is also uniquely designed to enable the 450cc engine to run at peak efficiency at all rpm. A straight intake port runs directly to the 39mm inlet valves, giving instant throttle response for immediate acceleration when you need it.
Enduro specific hydraulic clutch
The all-new durable hydraulic clutch gives a natural, light engagement with consistent behaviour for better control. It offers a light pull with plenty of feel, resulting in easier control of the engine – particularly beneficial when handling extreme conditions and lower-speed enduro riding.
Lightweight wide ratio 5-speed transmission
To match the most challenging enduro conditions, the WR450F runs with an optimised 5-speed wide ratio gearbox. Featuring gears with increased strength, this durable transmission is ideal for both technical as well as high speed sections.
Redesigned chassis
Offering improved control and comfort, the WR450F benefits from a redesigned chassis which has been developed from the race winning YZ450F. Tuned to offer a balanced rigidity, the downtube features a thickened upper section, narrowed bottom section and asymmetric engine mounts, ensuring more comfort and a better response when tackling tough enduro challenges.
Slim, compact bodywork
Slim, compact and ready to conquer. The WR450F’s narrow bodywork shrouds and mid-section offer freedom to move in all riding positions, while the flat seat features a new textured surface for optimum grip under hard acceleration and aggressive cornering.
Uprated KYB suspension
The WR450F is equipped with industry leading KYB speed sensitive front forks and a lightweight rear shock with enduro-specific suspension settings that give excellent feel and feedback. The front forks feature a hand adjustable compression damping adjuster for optimum precision.
Industry-first anti-theft ECU lock system
The Power Tuner app controls an industry-first anti-theft ECU lock system, unlockable only through the owners’ password for added peace of mind out on the trails or in the paddock. A few taps of the screen open the ‘Quick Tuning’ function enabling you to easily select ‘Smooth’ to ‘Aggressive’ engine settings to suit varying conditions.
Improved rear brake control
An updated rear brake setup features a new brake hose material, coupled with a revised caliper shape, smaller brake disc and changed piston diameter to offer a lighter overall weight, and improved control giving you better feel during challenging enduro sections. The changed lever ratio makes it easier to use, while an all-new removable pedal tip makes maintenance and repair work easier than ever.
Optimised ergonomics
The WR450F is a bike that is designed to give you the ultimate control. The rider triangle created by the relationship between the flat seat, footrest position and handlebar mounting location provides idealized ergonomics with easy rider mobility, enabling you to shift your body position rapidly and move your centre of gravity for optimum control when braking, accelerating or cornering.
Full enduro-ready specification
Fully ready to Enduro, the WR450F features an 18-inch rear wheel, enduro tyres, lighting, instruments, special ECU and a radiator fan. The fuel tank has a capacity of 7.4 litres, and there is a tool-less access to the airbox as well as an engine guard and enduro muffler to complete the enduro specification.
Low-speed control with new rear wheel sprocket
Improving low-speed control and reducing the ability to stall is a revised rear sprocket setup. During low-speed riding, the new T51 rear sprocket allows you to tackle long, demanding trails while also reducing stalling during slow, technical sections – giving you greater confidence at all times.
ENGINE
ECU Anti-Theft Lock
An ECU lock function through the Power Tuner App helps prevent theft and unauthorized engine start-up.
Enduro-Revised Four-Stroke Engine
The WR450F adopts the same high-performance engine from the YZ450F, revised for the varying speed and terrain of enduro riding.
Higher-Inertia AC Magneto Rotor
A revised AC magneto rotor increases inertial mass, reducing torque fluctuations for more low-end grunt and easier-to-use character.
Lightweight Lithium-Ion Battery
A high-capacity, lightweight four-cell lithium-ion battery provides consistent performance and minimal weight.
Low-Fatigue Throttle Control
Throttle control has been revised to require less effort, reducing fatigue over longer, more demanding enduro rides.
Noise-Reducing Air Filter Assembly
A new air filter assembly, with the same outer resonator as the YZ450F, reduces overall noise for more comfortable riding.
Reduced-Load Clutch Springs
Modifications to the clutch springs have reduced lever load for flatter characteristics, improving engine control at lower speeds.
Smooth-operating Hydraulic Clutch
The 2027 WR450F adopts the YZ450F’s hydraulic clutch, with a 15% reduced lever pull for reduced fatigue over longer rides.
Smooth-Power Cam Timing
