My Lifan GY6 looked similar, they just weren't very accurate when they assembled the rear subframe I suppose, but it didn't affect the handling of the bike... It was only the rear part where the seat and tail lights mount, we bent it with a pipe, it's pretty close now... Coast to Coast likely would have helped me out but I wasn't concerned with it and never mentioned it to them. I could only tell by looking at the reflector under the license plate compared to the tire.
