You may have a little bit better acceleration, too, since the gear ratio favors it.

As the variator completely opens up when at full throttle, the belt is still in the same position as a normal belt in the front, but now it will be higher up in back. The front:back ratio drive ratio is still shorter than it would be on a normal belt. This means, that at 8,000 rpm (or where ever your rev limiter is set at), the bike will actually be travelling slower than with the correct belt.

To make a long story short, you've basically traded some of your top end speed for acceleration.

Thanks for this info!
