has side racks for the Adventure. You can then decide what kind and what size bags to slap on. I went with a pair of E36 Givi cases. If you think the subframe can handle it, you can probably go with larger cases.
I can get my offroad helmet, roost protector, gloves, elbow guards, camel back, extra water, extra tools and 1st-aid kit in those two bags with a bit of extra room for snacks, extra socks and a extra shirt.
The neat thing about the Motech racks as that they are removable. No too pricy either
Plenty of pictures of them over on KTMTalk...
