The YZ250F engine is almost 450-like. It makes great bottom-end power, has a very strong midrange, and decent top-end. But it doesn’t have the over-rev the KTM and Husqvarna do, and because it signs off sooner than the Austrian bikes, it can’t carry a gear quite as long. Still, with the Yamaha’s excellent low-end power, it’s very user-friendly and can pull third gear in most corners. It offers the most tunability with the Power Tuner app and the handlebar-mounted dual map switch. The YZ250F is the loudest bike in the class—not only the muffler, but also the intake noise.
