l wanna know if it possible to change the seat height for my dirt bike I am not very tall. . .
will lowering the suspension hurt me when i'm riding

Yeah mate, To lower the rear shock u will see the spring. There should be two castlellated nuts on top of the spring, these r called locking rings. Loosen the top nut (use a screwdriver & a hammer or a preload tool) & once the top nut is loose u can wind the bottom nut up or down (wind it down to raise the bike & up to lower the bike). This is the quickest & easiest way to do it but this will make the suspension much softer, so if it is to soft u can get some lowering links for the back suspension or a smaller rear spring. As for the forks u can loosen the stem & triple clamp pinch bolts, & once u have done that u can lower the forks by pulling the forks upwards untill the desired height is acheived. This all may sound a bit confusing but if u r confused take it to a suspension specialist & they will be able to sort everything out for you. Hope that helped

it depends on the bike . Ifyou have links on your rear suspension you can add lenghth to them.Then slide the forks up in the tripleclamps.

yeah just lower the shocks/suspensions.it would not hurt much on riding anyway.
