2021 Yamaha YZ250F

With a higher-performing engine, an updated lightweight frame, and more, the YZ250F is engineered to race - and win - like a champion.

Features may include:

• Innovative and Upgraded Engine

The liquid-cooled, DOHC 4-valve, fuel-injected engine features a forward-positioned straight downdraft intake with symmetrical intake and exhaust ports. For 2021, the engine has been updated with new cylinder head featuring a new air intake system, an improved intake port shape, new exhaust camshaft profile, and an updated ECU—all to produce stronger mid- to top-end power and increased peak power, while retaining its class-leading low-end torque.

• Exclusive Power Tuner App

The free of charge and industry-exclusive Yamaha Power Tuner app brings the power of the GYTR Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.

• Adjustable Engine Maps

Two-mode adjustable engine mapping allows the rider to adjust engine character with the push of a button, making it easy to tune the YZ250F for changing track or weather conditions.

• Advanced Aluminum Frame

The YZ250F’s compact frame refines the instinctive handling that makes this Yamaha one of the best handling machines in the class. Large upper frame bracing improves rigidity and durability. The wider rear frame spars, and the YZ250F-specific engine mounts centralize mass for the best possible balance of bump absorption, stiffness and feeling of grip.

• Compact Body and Seat Design

The YZ250F utilizes compact bodywork from tip to tail, including a narrow fuel tank specifically designed for motocross demands. In addition to shaving weight, the body design provides more comfortable knee grip and control feel, with a seat shaped to give the rider additional room to move aboard the machine.

• Enhanced Mass-Centralization

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

• Adjustable Handlebar Mounts

The 4-position adjustable handlebar mounts are rubber-mounted to improve comfort and reduce handlebar vibration while the alloy handlebar centralizes overall mass.
