Hard to comment because if you shift at the wrong RPM and don't control your clutch well there could also with vibrations, but in general avoid the Chinese bikes due to reliability issues and lack of workshops who can fix them. I will only suggest bikes with ABS, and depending on what's your plan:

1. Strictly for practice and you don't mind upgrading soon: Dominar 400/Pulsar 200, will more closely reflect the actual situation in school, but may not be exciting enough for you to own them long

2. Something you can keep: Get supermoped like the SYM VF3i or Honda RS150R/RSX (both used under 4.5K). The Honda will need more care with its tensioner. These bikes will have a spot even if have another big bike, because they are practical and the best choice for cilok in traffic.
