Aprilia Tuareg has useful grab handles located under the passenger seat. These greatly help while maneuvering the bike. However, using any sort of rack-less luggage system will cover the grab handles, rendering them useless.
All edges on top rack side supports are chamfered. This prevents fraying of the haul loop, as well as any other straps, greatly improving their longevity.
The haul loop works great. It's easily accessible, even with luggage strapped to the bike and onto the top rack. Low profile ensures it will stay out of the way. Personally, I see no reason to remove it from the bike.
