There are many ways to carry a luggage on KTM 690 Enduro. One of my favorite setups is Touratech pannier racks, Wolfman Expedition Dry Saddlebags, Perun moto Side rack plates, Luggage rack and Extension plate.
We are currently working on Luggage rack plate for Honda CRF1000L Africa Twin. Rack plate will have some unique features, such as possibility to mount it in three longitudinal positions and some very useful features - predrilled holes for Rotopax cans or for Givi top box mount kit.
Recently, Boy from Netherlands sent me pictures of one of rare Kriega bags I don't own -Kriega Rally pack, on his Husqvarna 701 withPerun moto Luggage rack. It requires drilling to additional holes on the rack, but it fits great!
