i have test ride a few,

Dominar D400- vibration when throttle but smooth throttle no jerky, weird sound from ekzos when throttle

Leoncino 250 - vibration even on idle, throttle not smooth jerky, is this normal or the bike condition really bad?

waiting to test ride Cfmoto 250nk

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.

Not planing to get any moped at the moment. I do like adv160 but option for Bfull for future upgrade. I'm now aiming for clutch bike I can get used to shifting and braking

I would say Dominar makes most sense for you. First it is heavy, so that teaches you how to ride a heavy bike.

Second it’s common enough that all problems are documented…

Third.. you are gonna drop the bike for sure. Question is when. Jatuh bodoh, or grab brake slow speed and drop etc. Won’t be painful to drop it, plus lots of sliders available for it.

Finally.. not hard to resell it compared to the China bikes. I’ve seen a used 250nk on the market for 5 months…

aiming for dominar 400 but the same time gonna test ride 250nk, discover alot of mod part from taobao, gonna be fun bike but still reliable issue.

250nk looks good especially for the used price… but when time comes to sell.. even cheap there’s no buyer then going to be a headache
