Purchase advice for beginners

Hello people, my practical exam for the A – Schein (I can drive without a throttle) is soon at the door and I am looking for a suitable jump for this season with which I can start. I drove in the driving school both Naked and SSP. I like the Naked well, but I feel somehow more comfortable on an SSP with the lower sitting position. You don’t have the opposite pressure from the wind and you feel somehow safer. However, I am not averse also a I have a budget up to a maximum of 4000 euros. But I don’t know which Naked bikes are good and which brands you can get good for this budget. There you are in demand with your experience values. For the SSP I just throw a R6 Rj09, GSX – R 600, CBR 600 in the room now. What do you think of the above model Is there a seat, a beginner’s fit, etc? Greetings
