Update August 2023- we updated the side supports of ourTop luggage rack.New side supportsare now compatible withDucati Aux rear fuel tank. All info from this blog post is still accurate, as only side supports are changed - everything else remained the same.
OS-Rack loops can be bolted on the underside of the rack.
Standard Kriega OS-rack loops come with Kriega bespoke flat head bolt which can be replaced with M6 buttonhead bolt. OS-rack loops KTM fit come with M6 bolt which can be used to bolt the rack loops on the underside of the rack.
Depending on the bag and the orientation, rack loops can be installed in several positions.
To keep the bolt from unscrewing, it may be a good idea to use safety nut on the underside, like shown on the photo.
With OS-rack loops installed like this, it is easy and quick to install one of the US-Drypacks on the rack.
