Slide out the tube, then remove the pinch bolts. If the bolt holes mis-align it's bent. The nice part is that it's alloy so you can tweak it into shape jostby as described above. Be careful. I would assume a KTM clamp would not fit, as they have different width and offset. You can pull the whole thing and take it to a machine shop and see if they can straighten it. Shouldn't be a tough job with the right tools for the job.
