2021 Yamaha YZ250FX Powerful Dirt Motorcycle – Features and Price
Top Features
The Yamaha YZ250FXTM is an “out-of-the-box” Hare Scrambles and GNCC® competition machine based on Yamaha’s championship-winning YZ250FTM 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.
Yamaha’s Power Tuner app, which is available for free of cost and is industry-exclusive, brings the versatility and precise tunability of the GYTR® Power Tuner to your smartphone. Make immediate fuelling and ignition timing adjustments and upload them to the bike for maximum track-side tweaking, and alter pre-selected engine maps on the fly with the handlebar-mounted map switch.
The engine is based on the championship-winning YZ250F and has the same race-winning technology. To increase power throughout the rev range, the cylinder head, exhaust system, fuel injection, powertrain, and electrical system were upgraded. As a consequence, peak power is increased, power delivery is enhanced, and durability is increased.
The bilateral beam frame, which debuted on the YZ250F, will be used on the YZ250FX in 2021. In tight, rugged terrain, the forged section at the swingarm pivot and engine mounting brackets give an agile, lightweight feel while yet giving control in rapid passages. Yamaha’s class-leading KYB® suspension provides optimum control and traction, as it always does. The YZ250FX is ready to race straight out of the box, with an electronic starter, 2.16-gallon fuel tank, robust plastic skid plate, 18-inch rear wheel, and XC racing tires. With its engine, electronics, frame, suspension, slim and low body, and more, the YZ250FX is poised to place riders on top of the podium.
Engine
The high-performance liquid-cooled, 4-stroke, 4-valve, fuel-injected engine with front-intake/rear-exhaust has been optimized for wins in the highly competitive GNCC® and Hare Scrambles racing series. With a more fantastic compression piston, the intake and exhaust ports work together to provide a broader range of power without sacrificing top-end performance.
The famous Yamaha’s Power Tuner app, which is available for free and is industry-exclusive, delivers the GYTR Power Tuner’s power to your iOS® or Android® smartphone. The app lets the owners adjust air/fuel mixture, and ignition timing maps to tune engine performance for various track conditions, record race log information, and monitor a range of data like 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. Fuel and ignition timing are controlled by 3D-mapped electronic control in the fuel injection system, which is designed for cross-country racing.
Reversing the cylinder head and moving the intake and exhaust ports forward and back allows for a straight shot, downdraft intake, and straightforward exhaust port, resulting in increased engine performance. The appropriate gear is accessible for the broad diversity of terrain encountered in cross-country racing, thanks to a six-speed gearbox. In the severe circumstances of a three-hour GNCC® race, updated gearing ratios and a new heavy-duty, large-diameter clutch provide increased longevity.
The YZ250FX has a small, centrally placed electric starter system that reduces mid-race restart delays while also adding convenience. The device adds little weight and is powered by a high-capacity, ultra-lightweight four-cell lithium-ion battery.
Chassis/Suspension
In rugged terrain, the rider’s mobility across the bike is made more accessible by the minor bodywork. The gasoline tank holds 2.16 gallons, and the graphics are integrated into the body moldings for long-lasting excellent looks. An all-aluminum bilateral beam frame with a durable plastic skid plate offers strength, lightness, and durability for cross-country racing conditions.
A significant 50mm piston is included in the industry-standard KYB® fully adjustable spring-type forks with speed-sensitive damping and a KYB® rear shock. Both the knife and the rear shock have been extensively tested and adjusted for cross-country racing. Dunlop® cross-country racing tires are designed to enhance traction while also providing outstanding durability.
With excellent stopping power and controllability, a large 270mm front disc brake combined with high-performing pad material provides superb machine control and performance.
Additional Features
For additional rider convenience, a quick-adjust clutch, broad 55mm platform footpegs, four-position rubber-mounted handlebar clamps, aluminum handlebars, and a side stand are included. With the most extreme circumstances, the YZ250FX is also pre-wired for an optional radiator fan.
The air filter may be accessed without using any tools thanks to the air cleaner cover. The YZ250FX features a handy gasoline readout as well as an engine warning light on the handlebar, thanks to a WR®-style fuel level sensor in the tank. O-ring chain of superior quality is strong, long-lasting, and light.
