The shifter is from a XMotos SBF31.
I found the shifter on german ebay for 10€ brand new. I just had to prolong it for about 4-5 inches. Here's another picture:

I also ordered the two frame plates that carry the footpegs, just to keep them stored if i once decide to change back to the original setting. The plates will take another 5-6 weeks for delivery, the british guys sent me a mail to inform me, good communication with them.
