Doesn't that make your bike wallow in the corners? Man, I weigh 240, I've got my pre-load dialed up to 4 (ST1100).
After trying several different settings, this is what I found works for me (and several other forum members who've tried it).
On the ST1300's at least.
I found a couple things...when the preload is jacked up stiff, the bike puts more wear on the front tire, and the bike seems to rise up when taking off and lower back down when slowing down.
I didn't like this hobby horse motion.
I found that by matching my rear shock (some say undersprung) to my front forks, the rise and fall went away, the bike sped up and slowed down while it remained level, etc.
I weight 225 and always have a bunch of stuff in my saddlebags.
I set the damping on (2) full turns out from fully closed (stock setting is (1) full turn out)
Then I make sure the preload adjuster is full of fluid.
Then I turn the preload all the way open (counterclockwise), then start turning it back in (clockwise) until I just start to feel the preload working.
Its at this setting that I leave it (even when riding two up)
For years, bikes didn't have a preload adjuster, and folks did just fine with normal shocks.
The clicks on the preload adjuster are only 1mm per click. so with 7 being the default setting, you can see
Its a very small adjustment. I think mine is set at 4 clicks which is only 2 turns from soft.
My bike does not wallow in the turns, but tracks very well, keeps the rear wheel on the ground at all times, and turns into the corners
better than if the preload was stiff and the rear of the bike raised up (faster steering and nervous feeling)
It also rides very well in the wind on the softer setting.
Folks on the forum will try to convice you that you need springs, shocks, max preload etc.
After trying it both ways, I prefer my way. YMMV
I would suggest filling your preload adjuster if you have one, setting it on soft and just trying it for yourself.
You may find you've been missing a nice ride.
Several other members have tried this setting and were totally surprized at how much they liked it.
