Used 2018 Yamaha YZ250F Dirt Bike Motorcycle

2018 Yamaha YZ250F, 2018 Yamaha YZ250F CHAMPIONSHIP – PROVEN!

The 2-straight MX & SX West Champ and undisputed benchmark in 250 motocross bikes.

Features may include:

• Engine

Innovative Engine Design

The liquid-cooled, DOHC 4-valve, fuel-injected engine features a forward-positioned straight downdraft intake with symmetrical intake and exhaust ports. A compact, high compression combustion chamber delivers outstanding engine character with a focus on top-end power delivery.

Piston, Rod and Crankshaft Balance

A flat-top forged piston features a bridge-box design for additional strength with minimal weight. The piston, rings and DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss and contribute to quick response. The engine’s intake ports, cam profiles, high-strength connecting rod and optimized crank and counterbalancer all work together to produce potent high-rpm power with user-friendly delivery and exceptional reliability.

Advanced ECU and Fuel Injection

The adjustable fuel injection system uses a 44mm throttle body fed by a high-pressure battery-less electric fuel pump. This ensures optimum fuel atomization and air/fuel calibration for excellent rideability in a wide range of riding conditions. The system controls the volume of fuel injected and the ignition timing based on engine rpm and throttle opening, providing hesitation-free response and controllability.

• Chassis/Suspension

Bilateral Beam Aluminum Frame

A Yamaha’s renowned bilateral beam aluminum frame features compact overall dimensions that balance minimal weight with the strength and rigidity needed for race-winning performance. The frame’s swingarm pivot section and engine mounting brackets are tuned for stability, responsiveness and sharp cornering.

Mass-Centralization

The engine, aluminum muffler and fuel tank are positioned close to the machine’s center of gravity. This layout contributes to centralized mass for a lightweight handling feeling on the track. The wide 55mm footpegs help lower the rider’s center of gravity for improved machine balance, control and rider comfort.

270mm Front Brake

A large 270mm front brake disc is the same system fitted to the YZ450F™, and uses an aggressive pad material for exceptional stopping power and braking control. Out back, a durable heat-resistant rear rotor boosts brake durability.

• Additional

Embedded Graphics

Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.

Adjustable Handlebar Mounts

The 4-position adjustable handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration.
