Looks like a late-model Yamaha R6 track bike (note the lack of turn signals, etc.), so the slick would be just about right (unless you are running supersport, or it's raining at the track of course!).
Cool, neat to see it the back of a new Tundra. Hope the lack of bodywork isn't from a recent crash!
Earlier posters arer right though, stripped down to race weight (it's a light bike to begin with), it probably weights as much as the drivetrain on the Harley (!), so not a good tailgate test, but it's a start.
The recommended weight on the tailgate should be available information. They'll typically take quite a bit though. In an emergency situation, I put about a 450 pound bike on the back of my 1990 Toyota pickup without a problem.
In general though, I prefer a trailer. I have one that stands up and rolls vertically against the garage wall. As far as what to do when you unload the bike "on location", one possibility is that you might be able to get a single bike trailer that is either small enough, or will break down to be small enough to put in the back of the Tundra when you aren't using it!
But admittedly, that wouldn't be as cheap as a ramp...
