Youngest, almost 6, decided it was time for dirt biking to click finally and watching him you would never believe he has only been riding for a couple of days. He has had a good helmet all along but held off on the rest since they grow so fast. Older brother is still super cautious so haven't gone beyond boots and helmet with him so no handy me downs yet. I have never been very serious offroad riding so never went beyond boots myself. What is a good kids setup, what parts and pieces are good for them to have? Anybody have stuff left over that kids have outgrown? New is not important as again they grow so fast sometimes stuff ends up hardly being used.
