- These lid liners are for 45 L Zega Pro boxes or stock BMW boxes. I had them on my 2012 R1200GSA with OEM boxes and they fit perfectly. The bag dimensions are 16.5x10x3 inches. Please make sure they will fit your boxes before purchasing. They have very little use and are in great shape, but please note that you will need 8 screws and nuts to install them. The 8 corner brackets and straps are included, but you will need to get the hardware to install. I believe the Zega EVO boxes already have corner brackets installed, but don't quote me on that. Thanks for looking
