2019 Yamaha YZ 250F Single-Cylinder 249

2019 Yamaha YZ250F

TUNE, RACE, WIN

Powerful and reliable, and now with push-button electric start and the Yamaha power tuner smartphone app. The YZ250F was the ride of choice for Dylan Ferrandis, 2018 250 SX West Champion.

Features may include:

• Engine

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. A new, higher-compression piston and new intake and exhaust valving delivers outstanding engine character with a focus on top-end power delivery. For 2019, the cylinder is also lighter and angled more upright to improve mass-centralization.

Exclusive Power Tuner App

Breaking new ground in the industry – again – Yamaha introduced the Power Tuner app, which brings the power of the GYTR Power Tuner to your iOS® or Android® device. Using WiFi to connect 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.

New Electric Starter System

The 2019 YZ250F now features a compact electric starter system to minimize restart delays on track and add convenience everywhere else. Powered by a high-capacity and ultra-lightweight, four-cell lithium-ion battery, the system adds minimal weight.

• Chassis/Suspension

New Aluminum Frame

The 2019 YZ250F’s compact frame is completely new to further refine the instinctive handling that makes this Yamaha one of the best handling machines in the class. Larger upper frame bracing improves rigidity and durability, while wider rear frame spars and all-new engine mounts centralize mass for the best possible balance of bump absorption, stiffness and feeling of grip.

New Compact Body and Seat Design

The updated YZ250F features new bodywork from tip to tail, including a new compact fuel tank specifically designed for motocross demands. In addition to shaving weight, the new body design is narrow for more comfortable knee grip and feeling of control, and the seat is updated to give the rider additional room to move aboard the machine.

Enhanced Mass-Centralization

The engine, aluminum muffler and new, more 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 footpegs help lower the rider's center of gravity for enhanced machine balance, control and rider comfort.

• Additional

Adjustable Handlebar Mounts

The 4-position adjustable handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration, while the handlebar itself is lighter to centralize overall mass.

Embedded Graphics

Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage, with all new styling for 2019.
