KTM and Husqvarna regularly update their two-strokes, which usually receive similar revisions to the Austrian duo's four-stroke models as far as suspension and chassis changes go. KTM offers the 250 SX, 150 SX, and 125 SX, while its counterpart Husqvarna has the TC 250 and TC 125. The Yamaha YZ250 and YZ125 haven't received many updates over the past 13 years, but both bikes are still a rider favorite thanks to their nimble handling and excellent KYB SSS suspension components. TM is a boutique brand that takes pride in making exotic motorcycles. The Italian manufacturer's motocross lineup includes the MX 300, MX 250, MX 144, and MX 125.
