2014 Can-Am DS 450, GREAT VALUE - DS 450 With the DS 450, we have set new standards for the industry: the first no-weld, all-aluminum frame, hollow rear axle and inverted brake calipers. It?s a machine ready to race with less unsprung weight, more mass centralization and a better power-to-weight ratio. We invite you to ride it and tell us how we did. It?s OK, it?s understandable if you?re late getting back.
