Newbie: Help and advice when buying the first motorcycle

Hello together, for once: Hope this is the right place for my first post. I am just 21 and am currently doing my motorcycle driver’s license. Would you like to look around here which machine you would recommend to me and what I should pay attention to when buying and generally with the machine. How does it look with ABS? One must? Had looked around me once on various sides and have there e.g. these two jewels: a Kawasaki ER-6n, ride the same model also in the driving school, u and a Suzuki GS 500 F found. However, the Kawasaki is 4 hours drive away. Somehow there are used Kawasakis, at least in my price range (up to 3000€), only in the south of our beautiful country… Well, what do you think? Look forward to your comments. Greetings, Dennis
