Curious as to what tire pressure to use on the 2007 TRX90EX for my son and daughter. They both have their own. My son is 9years old and is pretty stout in weight. The girl is a month away from 8years old and is so light she doesn't squat the suspension at all.
Since we never rode before Christmas, I got all of our units at 4psi. But maybe that is way too much? We mostly do trail rides as a family in a single file follow the leader. Mostly packed dirt, but some loose gravel and occasionally some larger size riverbed rocks.
She never jumps on purpose. The boy jumps at any chance to get airborne. I am trying to keep him mostly grounded as he is too inexperienced to be jumping at all. As am I.

too much air pressure will cause them to be bucked off. The lighter girl i would go with less than the heavier boy. Since she doesnt squat the shocks at all you can use the tires to take some of the bumps. Just dont go to low where the tires will break the bead under normal riding. Hope this helps.
