When the front wheels of a sportbike are up against the trailer and loaded, the tie down points are to far back and it doesn't pull the bike forward, it pulls it down, or slightly backward... The "ramp" or "chock" or wheel stop, or whatever you want to call it at the front of the rail needs to be like 1 foot back... I am particular though, and would prefer to make it look factory, aka powdercoated black and look "Clean" not just a piece of scrap metal welded on that will rust and so forth... not sure if that last part is doable
