Aprilia rs 125 for beginners?

Hi guys, I’m just going to make my motorcycle guide rail and then want to get a motorcycle. now I don’t know which one. since I thought about aprilia rs 125, open, because I can drive a machine is 34 ps anyway. that’s why I thought it wouldn’t be bad at all.I’m already 23 years old.Many say I should get a real motorcycle right away. since I can only ride throttled at the beginning, it would be ok to have a small machine for the beginning. to take? would please me about your opinions, suggestions. thank you for your answers.
