YZ450F 2021 Yamaha Powerful Dirt Motorcycle – Features and Price

Top Features

More power and better control. Simply, the YZ450FTM 2021 is superior in every way. The YZ450F allows the rider to compete at their best, lap after lap, thanks to a more compact motor, a refined and balanced chassis, and enhanced ergonomics.

The GYTR® Power Tuner’s versatility and precise tunability are now available on your smartphone, thanks to Yamaha’s free and industry-leading Power Tuner app. Make immediate fuelling and ignition timing adjustments and upload them to the bike for maximum track-side tweaking, or change fueling maps on the fly with the handlebar-mounted switch. An all-new high-compression cylinder head, forged piston, aggressive cam profiles, and more work together within the ultra-compact new motor provide YZ450F riders the most pleasing mix of open-class power with controllability. It’s much manageable with the electronic start.

The revised main spars, triple clamps, and engine mounting locations on Yamaha’s bilateral beam aluminum frame help to concentrate mass and create an optimum stiffness balance between cornering sensation and straight-line confidence.

Yamaha’s spring-type forks offer industry-leading suspension performance right out of the box, thanks to precise, speed-sensitive damping. The YZ450F’s powerful engine features steeper valve angles, aggressive cam profiles, a high-compression piston with low friction rings, a longer connecting rod, a larger exhaust head pipe connector, a high-flow air filter, a more efficient breather system, and more—all while fitting beneath a smaller and lighter magnesium valve cover.

Gear widths and shapes increase shifting feel and precision without jeopardizing Yamaha’s famous race dependability. The flex qualities of the YZ450F aluminum frame provide riders with the best mix of precise cornering performance, traction, and bump stability. The 2021 YZ450F raises rider confidence to new heights by fine-tuning the chassis rigidity balance with adjustments to the lateral beams and engine cradle tube thickness, as well as the engine mounts, triple top clamp, and front axle.

The 240mm rear brake rotor conducts heat more effectively for more consistent performance under racing circumstances. At the same time, the stiff front caliper and compact rear caliper combine with the pads and discs to improve brake feel and controllability.

Cornering performance, traction, and bump absorption are all improved by the front and rear dampers, which are adjusted in tandem with the chassis. The rider can take the most of the engine’s tremendous power with greater confidence than smoother chassis movement.

Engine

The distinctive rearward-slanted cylinder light and compact design of the YZ450F are perfectly positioned in the frame for optimum weight distribution. Inside, the head has steep valve angles to allow for an even straighter down-draft intake port, as well as more violent cam profiles and a more giant diameter exhaust header joint that works in tandem with a higher compression bridge-box design piston, DLC-coated piston pin, and longer connecting rod to give YZ450F riders the best balance of class-leading power and outstanding control.

The Yamaha-created Power Tuner app, which is available for free, delivers the power of the GYTR Power Tuner to your iOS® or Android® smartphone. The app enables the owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for the track conditions, record race log information, and control a range of data such as maintenance and system diagnosis, engine run time, and more using wireless connectivity to talk to the bike’s onboard CAN-bus network. The rider may rapidly switch between preset engine maps—loaded and adjusted in the Power Tuner app—to accommodate changing track and weather conditions using a handlebar-mounted map switch.

The YZ450F is equipped with a small electric starter technology that reduces restart times on the track and adds convenience in other areas. The device adds little weight and is powered by a high-capacity, ultra-lightweight four-cell lithium-ion battery. By increasing controllability out of the gate and assuring the rider has the most incredible opportunity to win the holeshot and lead the competition into the first turn, LCS optimizes engine power faster; smoother racing starts every time.

To guarantee optimal fuel atomization and power for various riding situations, the engine breathes via a 44mm Mikuni® throttle body supplied by a high-pressure electric pump. In addition to saving weight, the ultra-compact throttle body provides superior mass-centralization. Even under the most demanding racing circumstances, the YZ450F has radiators oriented straight into the incoming air stream for improved cooling.

The transmission gears of the YZ450F have a large surface area, which is balanced against upgraded clutch components. The shift drum and selectors, which are all intended to increase longevity, also enhance the feel with a shorter and more direct stroke when changing gears. Yamaha’s unique exhaust pipe design improves mass centralization by bringing the exhaust pipe’s rear end forward, allowing the new muffler to be placed closer to the machine’s mass center. A broader combined profile also aids power development.

Chassis/Suspension

The YZ450F’s small aluminum frame enhances the natural handling that makes it one of the sharpest motorcycles in its class. Thinner main spar construction, thicker down tubes, redesigned triple top clamp, and all-new motor mounts have all been fine-tuned to improve the overall rigidity balance for outstanding handling, particularly in rapid, rough situations. The YZ450F has a sleek body from head to toe, featuring a small fuel tank built especially for motocross use. The rider can maintain their weight front during intense riding because of the lower, forward-positioned handlebar and more substantial seat.

The completely adjustable KYB® coil spring-type fork with speed-sensitive damping is the industry’s best. It offers excellent handling and bumps absorption. The KYB® shock in the linkage-type rear suspension offers damping characteristics that complement the YZ450F chassis.

The combination of a significant 270mm front disc brake, a robust caliper, and aggressive pad composition provides excellent braking performance and machine control. With a small caliper and 240mm rear rotor, the back system saves weight and improves heat dissipation. Each wheel’s cross-sectional shape is meticulously computer-aided refined to save weight without compromising durability.

Additional Features

The top triple clamp design balances stiffness for a better steering feel. In contrast, the rubber-mounted 4-position adjustable handlebar clamp provides comfort, reduces handlebar vibration, and allows for easy bar position adjustment.

Yamaha’s integrated graphics are incorporated into the bodywork for long-term durability and resistance to peeling and damage. An all-new 1-1/8″ aluminum tapered handlebars, more extensive but lighter footpegs, a quick-adjust clutch perch, attractive blue rims, and gold chain are all standard features on the YZ450F.
