I don't have or ever had crash bars fitted on my Tenere. But the fact that the Crosspro's are made of aluminium would concern me about their strength in a fall. In my experience with Steel verses Aluminium accessories fitted to Trucks, aluminium bends & fatigues ALOT easier than steel. Hence why the Tenere frame is steel so it doesn't break when loaded to the hilt.
In the event of a fall I fear the aluminium would do more damage than it saves.
Just some food for thought buddy.
