Seat problem

First of all, I'm new to this forum so hello to everyone.
I've had my cb500 for about a year now and for maybe the last 2 months, when my girlfriend is pillion, the seat comes loose at the back i.e. the plastic bracket unclips itself from the retaining bar. Has anyone else had this problem and is there a fix?
Cheers!

Welcome to the club mate!

I've not heard of this happening before to be honest, are there any cracks in the clips on the seat? When you clip the seat on does it feel firmly attached to the bike when you lift it up and down? It might be worth taking off the rear cowl so that you can see what's happening when the seat is fitted.

The seat does feel firmly attached and I can't see any cracks in the plastic. I'll try removing the cowl to see what's going on. I wouldn't mind if the girlfriend was a big girl but she only weighs about 7 stone.

When I first got my bike the seat wouldn't clip in at the back properly, kept coming out and it didn't look as though anything wrong with it, but I got another off Ebay and that's been fine. The only difference is that on the original seat the plastic looked as though it had just got a bit worn and it kept unclipping itself. Seats do come up on Ebay quite often.

cheers Stormy. I think this could be my problem. It's probably just worn with use. I'll keep my eye open for one.
