From the dealer's page

The Honda CRF450X may look like our CRF450R motocrosser (especially since we’ve updated the graphics this year), but look a little closer and you’ll see it’s really a totally different machine built especially for off-road, cross-country competition—think Baja 1000, or WORCs racing. It’s true that the CRF450X and our “R” model motocrossers share the same Unicam® engine architecture, but the CRF450X gets a wide-ratio six-speed transmission and a chassis featuring steering geometry more suited for off-road riding. Plus, there are plenty of other specialized touches too, like an 18-inch rear wheel for better off-road tire choice, a standard sidestand and hand guards, different ECU and fuel-injection settings, larger fuel tank, skid plate and more. East coast, west coast, and everywhere in between, the CRF450X rules the roost!
