Rotating Handlebar Clamps?

I noticed that I could rotate the handlebar clamps on my speed twin giving me a little extra reach,
Can any one see this being a problem please or has anyone else tried it?
Chars.

 

Thanks for that,
My thought process was along the lines of is it safe more than anything,
I am kind of surprised that Triumph don’t mention that it’s possible as it may benefit taller riders, yamaha do on the tracer gt.
Was as much intrigued to see if anyone else had considered it.
