The new Yamaha 2021 WR450F Off-Road Bike provides improved performance for tough enduro riding thanks to a more powerful, user-friendly engine and an upgraded frame. The full review of the Yamaha 2021 WR450F Off-Road Bike with its price and specification is written below.
Yamaha 2021 WR450F Off-Road Bike – Features and Price
New for 2021
New combustion chamber geometry with steeper valve angles, more aggressive cam profiles, a higher compression piston with low friction rings, a longer connecting rod, larger exhaust head pipe connector, a high flow air filter, a more efficient breather system, and more were added to the WR450F’s the already powerful engine—all while fitting under a smaller and lighter chassis.
The all-new flex qualities of the WR450F aluminum frame provide riders with the ideal mix of precise cornering performance, grip, and bump stability. The 2021 WR450F raises rider confidence to new heights by fine-tuning the chassis’ rigidity balance with modifications to the lateral beams and engine cradle tube thickness, as well as the engine mounts, triple top clamp, and front axle.
To enhance cornering performance, traction, and bump absorption, the 2021 WR450F sports improved front and rear damping that works in tandem with the upgraded chassis. The rider can use the engine’s tremendous power with more confidence thanks to smoother chassis movement.
Brake feel and handling are improved thanks to a redesigned, more robust front caliper with new pads and discs. The front brake rotor conducts heat more effectively than the rear brake rotor, resulting in more consistent performance under racing circumstances.
A more excellent contrast liquid crystal display with a gasoline usage indication is included on the newly designed small meter. Standard and Race are the two settings available on the meter. The speedometer, two trip meters, and clock functions are shown in Standard mode, while Race mode includes average speed, timer, and trip functionality, as well as low fuel and engine warning lights.
Top Features
The WR450FTM builds on Yamaha’s unique motocross racing platform with additional features and settings tailored to enduro riding. A new combustion chamber geometry with steeper valve angles, more aggressive cam profiles, a higher compression piston with low friction rings, a longer connecting rod, larger exhaust head pipe connector, a high flow air filter, more efficient breather system, and more combined to give WR450F riders a wide range of usable thrust with increased high-rpm power. They have a small starter motor and can be started with a simple press of a button.
The aluminum frame from Yamaha has all-new flex properties that offer riders the best mix of precision handling, grip, and bump stability. The structure is derived directly from the YZ450F to centralize mass and provide an ideal balance between cornering feel and straight-line confidence by changing the rigidity balance of the chassis with changes to the lateral beams and engine cradle tube thickness, as well as engine mounts, triple top clamp, and the front axle. On the WR450F, Yamaha utilizes KYB® spring-type forks, which have industry-leading functionality and are simple to adjust for a wide variety of situations. The WR450F is ready to travel where you want, when you want, thanks to precisely balanced ECU tuning and a Forestry Service-compliant spark arrestor-type muffler.
Engine
The rear exhaust and forward-mounted intake system on the WR450F has a cylinder head that works with the frame design to improve weight distribution. The engine has a straight intake tract, aggressive cam profiles, a high-compression “box bridge” piston design with DLC-coated piston pin, and more on the inside. The ignition and fuel injection maps for the WR450F have been tuned specifically for enduro riding and racing, resulting in exceptionally smooth and controlled middle power and longer-lasting pulling power at the top end.
The WR450F is equipped with an air filter that works in tandem with the modified intake tract length and a WR-specific muffler to improve the linear sensation of traction and drive. The WR450F damper is not only fully mechanical, eliminating the need for repacking, but it also has a US Forestry Service-approved spark arrestor. The WR450F has a big radiator with high cooling capacity, which is shared with the YZ450F motocrosser, as well as a cooling fan for constant performance even on the most challenging enduro runs.
The small electric starting technology on the WR450F simplifies trail restarts and adds convenience everywhere else. To guarantee optimal fuel atomization and power for a wide variety of riding altitudes and circumstances, the engine breathes via a 44mm Mikuni® throttle body supplied by a high-pressure electric pump.
The wide-ratio 5-speed gearbox on the WR450F is ideal for tight, rugged terrain and broad open fire roads. The transmission gears have a large surface area that is balanced against clutch components that have been upgraded. The shift drum and selectors, which are all intended to increase longevity, also enhance the feel with a shorter, more straight stroke when changing gears.
Chassis/Suspension
With frame spars and engine stands developed alongside the YZ450FX cross country racer to centralize mass for the more outstanding balance of bump absorption, stiffness, and rider feeling, Yamaha’s elegant aluminum frame offers high performance on technical, aggressive terrain sections as well as comfort for those long days in the saddle.
The WR450F has a sleek body from head to toe, featuring a big mass-centralized 2.15-gallon fuel tank. The body is thin to provide a more comfortable knee grip and control sensation, while the seat offers more excellent space for the rider to move about on the bike. Even the back fender is intended to give stiffness to the bike, making it simpler to move.
The industry-leading KYB® coil spring-type fork with speed-sensitive damping on the WR450F offers excellent handling and bump absorption, with mid-speed valving optimized for a better feel at slower fork speeds.
The massive 270mm front disc brake, along with aggressive pad composition, provides excellent braking performance and machine control, with tremendous stopping force and controllability, and has been redesigned for 2021. The 18-inch rear wheel of the WR450F helps to avoid pinch flats and provides extra comfort on challenging, broken terrain.
Additional Features
Compared to the YZ450F motocrosser, the WR450F has a broad, full-coverage composite engine guard, 18-inch rear wheel, big 2.15-gallon fuel tank, radiator fan, sealed O-ring chain, fuel level and engine warning lights, steel rear sprocket, and a high-mounted folding aluminum kickstand. A more excellent contrast liquid crystal display with a gasoline usage indication is included on the newly designed small meter. Standard and Race are the two settings available on the meter.
The speedometer, two trip meters, and clock functions are shown in Standard mode, while Race mode includes average speed, timer, and trip functionality, as well as low fuel and engine warning lights. The WR450F’s headlamp fairing and small taillight assembly help save weight and enhance the machine’s sporty, elegant appearance. Yamaha’s integrated graphics are incorporated into the bodywork for long-term durability and resistance to peeling and damage.
