First accident / unadapted speed

Greetings, I had an accident with my little one this week. I flew with from a left turn into a ditch. I know the route quite well, because I drove it at every exit. I don’t know why I missed the steering point anymore, because unfortunately I have a memory gap. Except for a few small things like neck pain, swollen ankles and a few small bruises nothing happened to me. Today I hardly notice anything about it. My motorcycle has ts is probably caught a little bit harder. It is currently in the workshop and next week we will see what to do, or if it is worth it. At first glance the frame looked ok. The forks are bent and at least one is broken. Handlebars and a footrest are also bent. The disguise is of course also over. First of all, I am glad that I survived the whole thing so well. Luckily, I had worn all my protective clothing. B Is on the helmet is so not big what happens, except on small scratches on my left boot. Unfortunately, there is now from the police the accusation that I was on the road at unadapted speed, so 100€ plus fees and 3 points. I don’t see that, because I have always driven the curves at similar speed. (about 80 at allowed 100 km/h). Do you have any tips on how to proceed or argue or can someone say something from experience about this. The left to the greeting
