Bolt pattern on Perun moto Add-on plates is made so plates can be fixed on most of pannier racks with Touratech sized hoops - with 18 mm tubing and 350 x 245 outer dimensions of hoop.
Nick recently sent me few photos of his KTM 1190 Advendure R with Perun moto Add-on plates mounted on KTM pannier rack. Great way to carry additional fuel in Rotopax cans.
Perun moto 790/890 Luggage rails were designed as a platform for small bags or Tool tubes. In several months of use, some bags proved to work great – Kriega US-5 Drypack, Mosko moto Fatty Tool roll and 4l Drybag. Standard size Tool tube proved to work great too.
KTM 690 Enduro R is redesigned in 2019. Tail section of the new model is different than on previous models and it is much more suitable for rack-less luggage. New Mosko moto Reckless 80 "Revolver" (or simply "V3.0") is a great choice for 690 Enduro.
