GG Contact GT25

[GT250]

Hello,
First something about me... I am 16 years old and from Germany. I visit the 11th class of a highschool and my favorite hobby ist motorcycling. I have a ktm sx 125 (`04) for motorcross and a Husqvarna sm 125 (`08, self paid) for the street.
But yesterday I get my GG Contact GT25 (`92 or `93) out of the basement.
My uncle gave it to me for my 6th bithday (2002). At this moment she doesn`t run since 5 years and now since 16 years (My uncle bought it new but drives it only for a short time in spain). But now to my question...

I searched on the Internet but i can`t find any replacement parts. If you know some websites with replacement parts oder bikes which have the same components, please post it here.

Here some pictures (not from me):
