Curve training Experiences and recommendations

Hello, dear, I have had my open motorcycle driver license since last year and have gained a Ducati Monster 797. Now, of course, I want to improve my driving and at the same time gain safety, here I thought about a corner training. Does someone already have experience with it and can tell me about it ? I am looking for a good provider near Heidelberg and surroundings here any suggestions? I would be happy about a feedback. Thank you very much!
