Qualifying choice Beginner’s bike

Hello together. And I’m just about to make my motorcycle driver license (A2) and imagine the big question which motorcycle it should become. As far as the price range is concerned, I’m at max. 1,300€. 20 years the motorcycle can also be old. Simply share your personal experiences; especially when it comes to size ratios, since I’m not the smallest with 1,90, and I’ve often read about A2 motorcycles that I like so far, that they are especially suitable for small bikes. Thank you very much in advance!
