Not sure about nvx, but it seems like adv150 is more trendy these days.

Anyways if you're budget limited you can try those wmoto scooters, like rt3 or the es250i. Es250 have twin channel abs, with a price tag of around 13-14k otr. Both are 249cc btw. Join the fb group for details of their usage or if there's any issues whatsoever.

Looking forward for the extreme 250 for the slightly bigger adventure scooter from them.
