Hi there,
Just to put your mind at rest, I installed my BMW shock over 2 years ago with a heavier spring from K'Tech (it needs it as you can't get the correct static sag), standard dog bones (you can't fit the after-market ones as the back wheel is then nearly on the ground with the centre-stand, as the BMW shock raises the rear) and have the front forks lifted through the yokes 20mm, so quite "extreme".
It steers brilliantly now and handles like a dream, but most importantly never had any stability issues on the bumpiest of roads and I don't hang around.
