How could it have taken so long? For years—decades, really—cross-country riders created the bikes they needed by adding fuel capacity, flywheel mass, skid plates, revised gearing, pipes, and even lighting to motocross bikes. Or they took another path by bringing a softly tuned dual-sport bike up to snuff. Along with other dirt-bike makers, Honda decided to fill the need in 2005 with the 449cc Unicam single-powered CRF450X. Carbureted, bottled-up feeling, and less than satisfactory in stock form, it’s finally been replaced by a new fuel-injected version for 2019.
