Transferring SF-Class from motorcycle to car in the past – still insure motorcycle cheaply?

Hello, I have a question about motorcycle insurances. I had already registered 2 motorcycles with the HUK24 in the past and have been in liability – if I remember correctly – down to 55%. After a wrong consultation – they told me at the time that I could not count on the use of my parents’ car, while I have been driving regularly since 2001 – I have the SF class of the motorcycle after the purchase of a car in 2007 on the Now I’m thinking of buying a motorcycle again. However, the computer on the site puts me at 125%. Is there a chance to return to my old class? Or can I get back to another provider with the old conditions? I wasn’t upgraded… Thanks and greetings!
