The BMW Vario cases are very good concept and design however the extensive use of plastic in the construction does not make the Vario Cases the most robust luggage solution.
A supplemental rear protection bar is the most effective way to protect the side cases in a tip over. The expanding Vario cases of course require a similarly expanding protection bar that can be used with the Vario cases in compressed and expanded mode and that is exactly what these protection bars do.
Once installed, a quick turn of the securing clamps top and bottom, allows you to extend or compress the telescoping bars as needed to match the mode of your cases. Simply retighten the adjusters and you're set. All in all a simple and easy way to help ensure that your expensive original BMW Vario Cases are not damaged in case of a tip over.
