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.
