yep, no binding or undue pulling.
I re-routed the electrical wires slightly and cable tied them into position.
Possibly the biggest influence was playing with the mirror block angle to ensure no undue strain at full lock. The stock mirrors adjusted from the new block angle easily enough and my replacement (Aprilia) mirrors had plenty of adjustment in reserve too.
There's always the choice of where to set the bars too - so, all in all, there's not too much brake line to spare but it's quite do-able.
Bike had done 15,000+ like this and nothing appears to have suffered
