jrider, I don't know that much about suspension, however like you I'm a dad with young kids and little bikes. As far as suspension work on the little bikes you might be hard pressed to get anything for them that would work for the kids. I found that upgrading to the "next" bike is probably the best bet. Once they are confident on what they have, put them on the next one. Don't be fooled by size either, my son went from a Yamaha PW80 to an RM65, he kind of turned his nose up at going with a smaller displacement until he let the clutch out and gave it a hit of throttle. Most of the upgrades for the little Honda's seem to be for adults on mini's.
