Because he may have a bike he doesn't want to race prep enough to ride in normal races.

There's guys out there with desmosdici's. Know of two. That don't want to race prep them. But would like to dice it up.

And they are licensed rider already. And do have the extra cash to pay $100. To turn a wheel in anger on their desmo streetbike. But not worry about someone chasing points and running them off the track.
