Beginner’s motorcycle

Hello I’m doing my 125 driver’s license (A1) at the moment. I’ve already looked around a bit on the motorcycles to have an exact idea which models come on my list and then in the fall who I have my driver’s license and the prices hopefully since the season is over to be able to hit. I have some questions about it. I have often seen old models that actually don’t have ABS but which are strangely indicated with ABS at Mobile. a reworked ? Actually only the new KTMs ABS in the 125 class should have or ? What is the difference between 2 and 4 clocks ? There seems to be both at 125ers . I heard the 2 clocks need after about 30,000 km larger maintenance work . Which models meet my criteria ? These are that the motorcycle is relatively low maintenance . They should go well forward (maximum speed is not so important) and is needed for a maximum of 1200€ . I hope that the criteria are not too high. I had picked out the Honda CBF,Yamaha YBR and Keeway Speed 125 and I do not know at the Keeway how much it consumes. What do you think of the models? How much maintenance do they need? And really consume them as advertised only around the 2.5 Litter? Consumption would be less important to me. It should be robust. I hope you can help me. Am I even right in the subforum?
