All Dual shock ad mono bikes have the same swingarm length. All of the shafts are interchangable. The paralever is about 4" (100mm) longer.
Grab a tape measure and go to a bike night. Measure the wheelbase of any modern 'dual sport' bike in the lot. You'll see that the BMW is anywhere from 4" to 8" shorter. Extending the swing arm does more for the smoothness of ride than increasing travel. It will also move the venter of gravity towards the front end, and you'll find the bike is a bit more balanced.
Just one man's opinion of course, but you can (and should) ride it with the standard rear end for 5K miles. just to see what its like.
