I had the same rear carrier on the back to fix the fishing basket, when off to the river Trent.
The front crash bar on my machine was a smaller unit which went all the way across the front. But it did the job when the bike fell over.
The bike was kicked over twice at the local sports centre, you could see the foot print on the edge of the seat where the dickhead had kicked the bike.
I then started parking the bike at the front entrance to the sports centre, which they let me do after the incidents.
