On this episode of On Two Wheels, the Dirt Rider testing crew heads to a top-secret midwest testing location to compare four of the most competitive off-road bikes on the market: The Honda CRF450X, the Beta 450RR, the Yamaha WR450 and the KTM 450 XC-W. These machines are drilled through an arduous combination of rocky washes and technical trails before being thrown into the night with only their stock headlights to guide them. Come along for the ride!
