I have been testing different pressures
on my SP500 HO and arrived at 8 as ideal.
It "floats" a little at high speed but seems
much more secure footed when cornering. I am
very curious to hear about what other riders have
found to be ideal. Recomended is 5#s all around.

 

7-8 here

 

I run about 4-5 in the rear and 6-7 in the front.

 

I go 4-6 depending on what I'm doing
7 and 8lbs sounds like a lot.
I mean the chances of blowing a bead probably doubles
espically when your "cornering"
