As long as everything has gone well for you, why not just make it a track bike and only ride there? Go ahead and throw away the lights, etc.... so you won't even think about going back on the street and just do track days. IMO, that's not an irresponsible solution at all. That, or sell it and pick up some dirt bikes for you and the kids. You all will have fun, reasonably safely, and you still get your riding fix.
