can consider Vespa? used ones la. im not sure can get <RM5k or not. not fast but nice to wander around the town.
i got mine for 4.5k for S125 2017. mileage was about 6000km+.
i was just lucky enough to get it off from a client i freelance with. in return with a few designs for free lol. i didnt like the color but i painted it + add blings

i think it's still possible, some rich people will try to get rid of it because they upgrade to bigger bikes.
Sprint, Primavera and later models are generally expensive. older models like LX150, S125 possible. try joining fb groups!
