The fork blade is not curved or bent - it is an optical illusion created by the spokes while you eyes are focusing on the fork. It does look like there is little or no clearance of the front tire by the downtube, however. Hard to tell when the bars are turned inward like on the photos, but maybe the fork is bent at the steerer, and there is not enough clearance to even rotate the bars further without the tire hitting the downtube.
