After months of weekly abuse, the YZ gets an A-plus for reliability. It still feels amazingly fresh and has only required the requisite oil- and air-filter changes. Ridden back-to-back with the competition—though not in formal shootout mode—the YZ feels as though it lacks the outright power and light, nimble handling of some of its competitors. That being said, the Yamaha always feels planted, stable and less busy than some others in the class. Credit goes to the aforementioned swingarm/link changes, the speed-sensitive, 48mm KYB fork and excellent bite of the Bridgestone tires; combined, they take the guesswork out of riding the YZ quickly.
