Thanks a bunch Cortez.
I have looked all over the net and could not find this information.
The reason I asked the question was, my wife bugs me wanting to ride with me. I do not enjoy riding two up but, I give in some.
Me and the wife together run about 350, so the GT should handle us ok.
Just punch the preload all the way up and you can even do some spirited riding that should
scare her enough to leave you alone..
I've done a short ride on my DT300 with a 250lbs friend, and with me riding the total load was around 450lbs.
My Kawasaki would bottom out even with the preload on 7/7 with that guy behind me (not like that, damnit),
and the DT would not, even with the stock preload settings (about half of available).
Since then, I've dropped the preload one tooth down, so it's not something like 2/5 for my 200lbs of fat and
it's fine.
