[QUOTE="Fred W, post: 1450484, member: 3828"] Hmmm. Sliding the fork legs up would steepen the steering angles, which [I]should[/I] make the front end less stable and more prone to oscillate. It would make the bike turn-in quicker. Adjusting the preload is the same thing as ride height. You can raise or lower either end of the bike by increasing or decreasing the preload adjusters. That is what preload is there for. It won’t affect the spring’s rate or stiffness at all. It can’t. Both of my FJRs have always wobbled at hyper-legal highway speeds with a top case and no passenger. I generally only put the top case on when I have a passenger, but have sometimes wanted the extra space for solo vacation trips, and always feel it then. Never noticed it at slower speeds though.
