A few months ago, Yamaha invited us out Glen Helen to get a chance to test ride the pre-production 2014 YZ250F, allotting only three short hours to get a first impression aboard the all-new machine. Now with a sufficient amount of bikes in the country to both provide the media and dealerships, Yamaha flew us out to Monster Mountain MX Park in Alabama this week to fully shake down the production YZF, which by in large is exactly the same as the pre-production model we initially rode. With two days of riding under our belts aboard the bike, we came away impressed with the performance, as well as the numerous changes and updates. Our annual 250cc Four-Stroke Shootout in a few weeks is definitely going to be interesting. Stay tuned… And if you want to see our impression on the pre-production model, click the link below.
