1 YEAR FACTORY WARRANTY. In developing the DS 450, we truly reinvented how a sport quad is built. With the industry’s first no-weld all-aluminum frame, hollow rear axle and inverted brake calipers. We then pushed the concept even further with two terrain-specific X models. The tight-woods racing DS 450 X xc and motocross-inspired DS 450 X mx. Both are equipped with industry-leading features and are ready to race right out of the box. You can read on. But eventually, you’re just going to have to ride one.
