Sure thing, I’ll take the fender off tomorrow to get better more detailed pictures.

I love the seat but I also didn’t have problems with the stock seat. I feel it does have more of a curve on the back part and slightly more cushion, so it may help you with your issue.

Bikekraft, could you post a picture of your solution that fits a 180x200mm license plate?

So what I did was cut a piece of angle aluminum and attached it with nut and bolts to the pre existing bracket that comes factory on the slim rear fender. Then using flat aluminum pieces I made a bracket to attach to the angle aluminum. Just had to bend one piece of aluminum to the curvature of the fender. I also removed the stock plate light from the factory plate holder and installed it between the curved aluminum and fender using double sided tape. I spray painted it black but after a year and half it’s chipped off. Not the pretiest but u don’t even see it when plate is installed.

Thanks for the pictures! I’ll do a similar solution.
