I've also got a good left one but need the right one too.

I dismantled my damaged right one (lots and lots of blasted screws) and managed to glue it together. It isn't a good job, and it won't take another fall, but its all right holding a light load.
The lock bit is tricky, once opened all the bits jump out at you, then scatter themselves around the room, and theres some small bits.

I have tried extensively to get an inner panel, as this is the only bit that is broken, but its simply not sold, so you need to replace the whole pannier.

So i guess the message here, is if anyone is considering buying panniers and has read this, they shouldn't be stupid enough to fork out cash for the Yamaha crap.
The panniers are functional, very convenient, but are simply not suitable for motorcycles

I am looking out for 3rd party genuine motorcycle hard panniers.

I would however consider the Original equipment Top box
