HOW DO WE CONVINCE YOU THESE QUADS ARE READY TO RACE OUT OF THE BOX? ITS SIMPLE: RIDE ONE.Last year, the DS 450 and the DS 450 X were introduced, each offering the lowest weight, lowest unsprung weight, most power and most mass centralization. This year, we've refined the X concept even further with two new terrain-specific models the 50 inch wide DS 450 X mx and the tight-wood racing DS 450 X xc. Both offer the same industry-leading attributes. Both are ready to race right out of the box. And together they give you the opportunity to ride the way you want to ride. Track or trail.
