Dirt Rider Magazine took a 2011 CRF450R and ran it through Glen Helen’s intense HYR Endurance Series. The 6, 12 and 24 hour races added up to 42 hours of dusty ridges, windy singletrack, rough fire-roads, rock laden creeks and epic moto—all of which make the three events something to be proud of if you finished. We made it to every checkered flag with a dedicated team and one tough motorcycle. These are the parts that we felt were necessary to help get us through 42 hours of exciting off-road racing!
