Ask for Help – Motorcycle Stirred

Good evening, before people write to me, fault themselves, idiot! I know! Yes, I made a mistake, I totally see and if it doesn’t make me pay for it myself. Already before. I got enough trouble, etc. … believe it. Anyway, I wanted to ask anyway. The following situation: A buddy offered me to try out his 125s (not my first time driving a 125s). I said cool thanks … go off normally. . Everything okey, as I said before had already driven there bitsl experience (I never drive again!). There was then a curve …. I was not too fast, but there were stones … well … I just slipped. I did not happen anything, very slow driven. But the right side of the machine (Megelli 125er) looks bad bits. So 2 fairing scratched, turn signals off and brake bent. And also probably the front brake or brake disc is a bit bent. It just grinds while driving. Yes …I’ve built shit. Let’s not talk about it, of course my fault! My buddy was pissed off at the beginning of course, but that’s okay again. I said I’m paying everything. Of course! The machine is new, so he has a guarantee on it. But he didn’t mean that if you slipped (even if he said he would have slipped). My buddy said that would cost about 600€ (yes, that’s fine, I pay, myself). But there is insurance technical k another possibility? So I have a liability insurance, but just no A1 driver’s license. -.- I ask you to help me objectively. What are there possibilities? Can another buddy with A1 and accident insurance say he has driven? Would they pay? I thank you for every suggestion! And again. I will never try something like that again! It’s a lesson to me!!!
