Those will indeed fit over the 650 oem plastic guards??? Are the new 17 oem guards the same as the gen 2 guards? Suzuki loves to reuse parts or do the new 650s get the new 1000 guards? Sure looks like you need to have the OEM bars as the mount points are exact on the ends and then on the triple clamp mounts. Any aftermarket bar will have a different spec for sure.
