Later models Varaderos have an absolutely crap rack that is next to impossible to get secure places to fit bungees or luggage straps. So, I took a chance on an offer from Iainnic in the sale/wanted forum and bought a Touratech rack extension for a TA700 hoping it would fit my 07 Vara. Good news is that, with very little modification, it does.

All I had to do was drill the 4 mounting holes slightly larger to take M8 bolts and then it simply bolts through to the existing 4 captured nuts that retain the plastic cover or the mount for a top box plate. I do need to get some countersunk bolts to neaten up the job. My pics to follow when I have found my phone camera.
