2019 Yamaha YZ250F Dirt Bike – Features and Price
The Main Functions
The 2019 YZ250F is equipped with a brand-new engine, new frame, new body, etc., ready to stand out from the race, with unique features of the 250cc class. The 2019 Yamaha YZ250F Dirt bike uses a compact starter motor and ultra-light lithium battery to provide a convenient button start function for the racing track, which can be quickly restarted under pressure and comfortable ride without the clock.
Yamaha has created a new situation with the Power Tuner application, bringing the flexibility and precise adjustability of GYTR Power Tuner to your smartphone. Immediately change the fueling and ignition timing and upload it to the bike via the onboard WI-FI system to achieve excellent trackside adjustments. Yamaha continues to use spring-loaded front forks with exquisite, speed-sensitive damping to obtain industry-leading suspension performance immediately.
The updated cylinder head, piston, cam profile, cylinder geometry, and many other features provide the YZ250F rider with the best balance of high-speed power and a wide range of available power bands. Yamaha’s bilateral beam frame has a new main spar, engine bracket, and engine mounting location to further concentrate mass and achieve an ideal balance between turning feel and straight stiffness.
Engine
The liquid-cooled DOHC 4-valve fuel injection engine has a forward and downward direct intake device with balanced intake and exhaust ports. New high-compression pistons and new intake and exhaust valves have excellent engine characteristics. For 2019 Yamaha YZ250F Dirt bike, the cylinder is also lighter and the angle is more upright to improve mass concentration.
The flat-top forged piston adopts a bridge box design, which increases the strength with minimum weight. Pistons, piston rings, and DLC-coated piston pins, and offset cylinder configurations all reduce friction losses and contribute to rapid response. The engine’s air intake, cam profile, high-strength connecting rod, and balancer work together to produce dominant high-speed power.
The adjustable fuel injection system features the new 44mm throttle body, is fueled by a high-pressure electric fuel pump, and injects fuel through a new 12-hole Denso injector. It ensures optimum fuel atomization and air/fuel calibration. The more compact throttle body is also 12% lighter than the previous unit.
Innovative exhaust pipe design improves mass concentration and power development characteristics. This layout was updated in 2019, moving the rear end of the exhaust pipe forward and enabling a new muffler, which is located closer to the bicycle’s center of mass. The more modern radiator is larger and more directly inclined in the incoming airflow to improve cooling in the most demanding race conditions.
The gearbox, flaps, and shifting mechanisms are designed to smoothly change gears and improve durability under the demanding requirements of motocross racing, even when using lighter gears and gear selector drums in 2019. The updated 2019 Yamaha YZ250F Dirt bike also has a larger diameter clutch.
Chassis / Suspension
The compact rack of YZ250F in 2019 is brand new, which can further improve the automatic operation, making this Yamaha one of the best processors in its class. The broader upper frame support improves rigidity and durability, while the full rear frame beam and the new engine frame concentrate the mass together.
The updated 2019 Yamaha YZ250F Dirt bike has a new body from start to finish, including a new compact fuel tank designed specifically for off-road motorcycle needs. In addition to reducing weight, the new body design is also narrow, and the seat has been updated to provide riders with additional space to board the machine.
The engine, the aluminum muffler and the new, more compact fuel tank are all located close to the center of mass of the machine. This layout helps to concentrate the quality, to have a light sense of control on the track. The 55mm full footpegs help reduce the rider’s center of gravity.
The large 270mm front brake disc is the same as the system installed in the YZ450F and uses aggressive brake pad materials to provide superior braking force and brake control capabilities. Careful computer-aided optimization of the cross-sectional profile of each wheel can save valuable weight without sacrificing durability.
Additional Features
The 4-position adjustable handle mount is rubber-mounted, which improves comfort and reduces handle vibration, while the handle itself is lighter and can concentrate overall weight. Yamaha ’s unique embedded graphics are built into the body to extend durability, resist peeling and damage, and adopt all new styles in 2019.
The 2019 Yamaha YZ250F Dirt bike contains essential details, including 1-1-1 / 8-inch aluminum, tapered handlebars, 55mm full spikes, quick-adjust clutch highs, stylish blue wheels, and gold chains. The sleek new air filter cover helps prevent contact with the quick-release quarter-turn Dzus air box fasteners and provides a tool-free method of servicing the air filter, which is located in front of the bicycle to avoid the impact of the rear wheels.
