Who doesn't like a good ol fashion head to head battle between two pre-mixed moto machines? In this video we took our 2017 KTM 250 SX and 2017 Yamaha YZ250 two-strokes and let our test riders ring them out at a few different tracks. Both machines have several standout strengths and our more than a blast to ride. Listen to the sweet two-stroke sound and hear what each tester had to say about the differences between each machine. Check out the July issue of Dirt Rider Magazine for the complete test.
