The FZ6-R is a different bike, so the fairings aren't compatible.
Try bike breakers/ scrapyards, although the fairings are generally the first bits to get broken in an accident, so getting replacements is always difficult.
I have seen posts on FB where people have sourced similar bits from AliExpress or Power Bronze, but I have no idea how good they are.
You may still be able to get OEM parts from Yamaha, but, from what I've heard, they are *expensive*!
