there are chinese replicas available.
But they have no rubber mounts but ones from solid plastic. I did not know how long they will last
Also the Yamaha YBR 125 from 2006 has the same indicators.
Beside this some Aprilias and of course some other Gileras from that time have them.
They are from CEV. There should be a number on the case. Maybe searching after this will end in more sucess.
There are some slightly different version out there. German Saturnos have longer rear indicators than others.
There are some with 3 grooves and some with 4
good luck, Joachim
