cracking

I bought this from Yamabits in June this year. It's already started to crack. Don't waste your money on it chaps (and girls) looks good but seems a bit flimsy. Any one else experienced this issue? What causes it? I've never carried a pillion so I know it's not because anyone has sat on...

As per the title this unique plate is for sale, the plate is currently on my MT07. Please DM if you are interested. Looks cracking on the bike! Cheers Matt
