When I had my Kawasaki suspension set up at MCT, it was set up for my weight and my riding style. I said that I occasionally took a pillion so that was also allowed for such that all I needed to do when taking a pillion was add additional pre-load, primarilly to the rear. It was however, explianed that setting it up like that meant it was a compromise both when riding solo and when riding 2 up as, ideally, the dampling would also be adjusted between pillion and solo.
From that, I'd suggest that the simple answer to your question is yes, but that assumes that the factory settings are about right for you solo. I've NEVER ridden a BMW where the factory settings are right for me. Even with the ESA, I never ran the pre-load in solo mode and rarely used comfort (gentle damping) unless the road was particularly bumpy.
