2023 Yamaha YZ250FX Dirt Motorcycle – Features and Specs
Key Features
The 2023 Yamaha YZ250FX Dirt Motorcycle relies on the same race-proven technology found in the YZ250F, which won the championship, to power its high-performance four-stroke engine. The engine has been fine-tuned for off-road performance by adjusting the intake duct, intake port, exhaust camshaft profile, silencer, and balancer weight location, among other things. These adjustments complement one another to boost performance and usability across the board, making the vehicle more capable and adaptable in various conditions.
The YZ250FX chassis is an example of cutting-edge technology and design. It is made of high-tech aluminum and has a bilateral beam frame construction, and its flex properties have been fine-tuned for optimal performance in competition. In tight, challenging terrain, the bike feels light and responsive thanks to features like the forged section at the swing arm pivot and the refined engine mounting brackets, and it maintains accurate control at high speeds. Yamaha’s industry-leading KYB® suspension is standard on the YZ250FX, ensuring that you have complete command and grip no matter how rough the terrain becomes.
The Power Tuner App is an innovation from Yamaha that allows for precise performance adjustment. With this free app, riders have the versatility and particular tuning capabilities of the GYTR Power Tuner in the palm of their hand, regardless of where they are. It permits on-the-spot tweaking for peak performance by adjusting fueling and ignition timing, followed by an immediate upload to the bike.
The 2023 Yamaha YZ250FX Dirt Motorcycle’s performance may be tailored to the rider’s preferences thanks to a button on the handlebars that toggles between two fuel injection maps. The Yamaha Power Tuner app may be used to load and fine-tune these maps. One map is optimized for high-speed, high-traction situations, while the other has a more refined engine personality for low-speed, high-speed situations.
The YZ250FX has a high-performance braking system intended to stop quickly and precisely. A vast 270mm front rotor is coupled with an aggressive brake pad compound and a stiff front caliper with larger pistons to create this system. With a 240mm rear rotor with a lightweight caliper and hanger, unsprung weight is reduced, and braking performance is further improved.
The YZ250FX performs well and has a beautiful paint job that reflects its racing heritage. The quality Yamaha Blue paint and dark blue graphics not only give the vehicle an air of superiority but also protect it from wear and tear. The motorcycle’s radiator vents are black, giving it a more menacing and kinetic appearance.
The electronic starter, large 2.16-gallon fuel tank, sturdy plastic skid plate, large 18-inch rear wheel, and high-performance Dunlop® Goma MX33 tires ensure that the YZ250FX is a trail- and XC-track ready straight out of the box. It’s a war machine built to ensure success.
Out-of-the-Box Hare Scramble/GNCC Racer
Based on the championship-winning YZ250F that features Yamaha’s revolutionary front-intake, rear-exhaust, liquid-cooled, DOHC 4-stroke power plant with an added sixth gear, wide ratio transmission, and a range of cross-country upgrades, the YZ250FX is an “out-of-the-box” Hare Scrambles and GNCC competition machine.
Engine
To ensure victory in the GNCC and Hare Scrambles racing series, Yamaha fitted the YZ250FX with a state-of-the-art liquid-cooled, fuel-injected, four-stroke engine. Its excellent compression piston and innovative front intake and rear exhaust layout provide a more comprehensive power range without sacrificing acceleration. The innovative engine architecture is built to withstand the rigors of extreme off-road racing conditions.
The intake is at the front of the engine, and the exhaust is at the back, thanks to the novel configuration of the cylinder head. The engine’s efficiency and performance are both improved by this configuration because of the downdraft intake and the straight exhaust port. This technological wonder exemplifies Yamaha’s determination to revolutionize the off-road engine industry.
When it comes to fine-tuning, nothing beats the Yamaha Power Tuner App. This free software is available for both iOS and Android smartphones, and it unlocks the full potential of the GYTR Power Tuner. By connecting to the bike’s internal may-bus network wirelessly, riders may adjust the bike’s air/fuel ratio and ignition timing maps for optimal performance under varying track conditions. In addition to keeping track of essential data like service schedules and system diagnostics, the app also lets you record statistics from your races.
A map switch positioned on the handlebars allows riders to adjust to new environments quickly. Two different engine maps are available for use, and both may be customized using the Power Tuner app. The fuel injection system is electronically controlled with 3D mapping to provide optimal fuel and ignition timing for off-road competition. With one map optimized for high-traction situations and another optimized for low-traction, riders can access a wide range of options.
The YZ250FX has a six-speed gearbox to help it adapt to the varying terrain of cross-country racing. It guarantees that motorcyclists always have the tools they need, which boosts their flexibility on the course. Even in the harsh circumstances of a three-hour GNCC® race, the updated gear ratios and a sturdy, large-diameter clutch provide long-lasting performance.
The YZ250FX has a centrally located electric starting motor. This small system, placed centrally, reduces race restart times and improves riders’ experiences in several ways. A high-capacity, compact four-cell lithium-ion battery provides consistent power with minimum added weight. Yamaha’s dedication to providing the best off-road riding experience possible by fusing state-of-the-art technology with practical, race-proven solutions is reflected in this system.
Chassis/Suspension
The 2023 Yamaha YZ250FX Dirt Motorcycle takes a page from the best-selling YZ250F and adds a cutting-edge bilateral aluminum frame for further strength. For the rigors of cross-country racing, this frame’s mix of power and low weight is essential. In addition, a rugged plastic skid plate is included for safeguarding the vehicle’s undercarriage against trail hazards.
The best suspension in its class further boosts its already impressive performance. Known for outstanding quality and reliability, KYB’s fully adjustable spring-type forks and KYB rear shock have been fine-tuned and tested to satisfy the rigorous requirements of cross-country racing. This level of suspension refinement offers superior handling and control, letting riders confidently take on a variety of terrains.
The YZ250FX’s high-end brakes provide powerful stopping ability and responsive handling. This setup uses an aggressive brake pad compound and a stiff front caliper with bigger pistons. Combined with a large 270mm front rotor, it guarantees consistent and quick-stopping power. A 240mm rear rotor and lightweight rear caliper and hanger work together to reduce unsprung weight and improve the bike’s braking performance.
The YZ250FX has compact bodywork for maximum rider comfort and handling. This layout makes it simple to maneuver the machine, even in challenging environments. A wider cap hole makes filling the gasoline tank, which holds 2.16 gallons, a breeze. Further, high-quality graphics are integrated flawlessly into the body moldings, maintaining their aesthetic value even under extreme racing circumstances.
The tires of the 2023 Yamaha YZ250FX Dirt Motorcycle are designed with off-road competition in mind. The Dunlop® Goma MX33 tires provide an ideal compromise between traction and durability. Yamaha’s dedication to providing riders with the best possible grip and durability in off-road racing conditions is shown by their selection of these tires.
Additional Features
Yamaha has designed the YZ250FX with the rider’s comfort and convenience in mind by including many useful features. These features include a four-position rubber-mounted handlebar clamp, a broad 55mm platform foot peg, and a quick-adjust clutch. The aluminum grips enhance both long-term use and rider comfort. The included side stand allows for more adaptability. The YZ250FX is also equipped with a pre-wired optional radiator fan, essential for sustaining extreme riding conditions.
The 2023 Yamaha YZ250FX Dirt Motorcycle is built for simple repairs and maintenance. The air filter may be easily accessed without any special equipment, thanks to the air cleaner cover. The YZ250FX also has a low fuel warning thanks to a fuel level sensor in the tank reminiscent of the WRs. More information about the bike’s performance is available at a glance thanks to an engine warning indication mounted on the handlebar.
The YZ250FX is built to last, as seen by including a sealed O-ring chain. This top-notch chain is durable and trustworthy, but it also weighs very little, so it doesn’t negatively impact the bike’s speed or performance. Yamaha has made the YZ250FX a high-performance bike that is also easy to operate and maintain by including these thoughtful features in the design.
