Hi my name is Craig i own a Gas Gas TXT PRO 250, i run a irc tyre on the rear and a michilin on the front i have been riding trials for one year now and improving all the time. I have been running 4psi in the rear and 6.8psi in the front in dry conditions is this correct ? Thank you for your help in this matter.

It sounds about right although maybe drop the front down a bit to 5.

Thanks for the info i will drop the front tyre pressure down a bit and see how it feels. Craig

I run 5f 4r on my Scorpa which is also on Mich front, IRC rear. We don't ever see any rocks around here, but I'd run a little more if I was to ever see one!
