Design an image of an aggressive, custom-built chopper motorcycle roaring down a deserted highway. The bike has a low, stretched-out frame with a menacing appearance, featuring chrome accents and flame decals. The large, wide rear tire kicks up dust as it speeds along the road. The rider, wearing a black leather jacket and helmet with a dark visor, leans back confidently. The setting is a vast desert landscape under a dramatic sky with storm clouds rolling in, creating a sense of raw power and untamed freedom.
