That cover, on the front caliper...I dont know the actual name, but drag racers use it to control front end height.
You use what amounts to a small ratchet strap/s and can smash the suspension down, or allow it to raise a little. You still get some suspension action, but very limited due to the length of the strap.
Its like this:

If you think bikes like ours are fast off the line, and they are, but if you take even our Ninjas and lower them, and lengthen... holy crap.
I would imagine you could launch a Ninja 1000 at near full throttle with a good rear tire, longer arm, and lowered.
