It didnt happen all at once, but over the course of many months or maybe a year now. The first crack to develop was up the right (picture orientation) side, which met up with a second crack 1cm along, then that small section fell out, later the two up the centre , where that section fell away, then the one up the left.. As you can see it is a red tail that i had sprayed black when i dropped the bike a few years ago and damaged the oem black one... which now looks to be in less of a sorry state than this one!..
Im not sure if this is caused by my bum from sitting too far back in the seat?.. even though people have bum stops on their tail sections so Id would have assumed it should have been able to take the force.. My other guess was that the fairing I bought had cracks in it that i didn't notice that must have surfaced over time and use... So I am thinking about buying a chinese tail top fairing and having it painted or attempting myself... hopefully that doesnt crack too!
