hey mate dont think you will be able to get a sticker kit for that thing not a commom plastics shape so think you ight have to stay with them or just take them off
they look like plastics off a yamaha tt-r125 so ask for a tt-r125 sticker kit.
but to be sure make sure that they are tt-r125 plastics but im pretty sure they are.
hope this helps=]
Your going to be limited even if you find a kit to suit
there not a bike that gets modded hence the no arfter market bits same as the tt-r
id go with the airbrush idea tho may cost a few bob
better yet forget about what the bike looks like and ride it
in 12 months she'll be banged up and scratched anyways
