Both are in good shape, my kids just  outgrew them before they learned to like riding.  Extra set of new plastic for the 50 and a FMF exhaust on the 70.  I'll even throw in some small gear if it will fit your kids.  I think I even have a set of training wheels for real little kids.  I'm pretty motivated so shoot me a reasonable offer.  I have pinks on them but DMV will want stoopid money to register them as they are a few years unregistered now.
