Ready for a peek at photos and specs on the new 2013 KTM models? Two years into the new generation of SX models, KTM says, "We are pushing even harder to underline our clear intention of being the world-wide leader in motocross." That's a pretty bold statement, but they've been charging forward, while other brands have been relatively idle during recent years.

Highlights for this year? The SX model range gets new bodywork, updates to frames and suspension, and an all-new engine for the 250F. The 350 powerplant has been reworked, and the new 450 joins the line as a full-time member, rather than a limited edition.
