Martin Elvis at Harvard University describes how the SpaceX Heavy allows us to reach over 40% of the asteroids where before we could reach 3%. This is because the SpaceX Heavy allows higher speeds (delta-V aka change in velocity) to be reached.
An orbitally refueled SpaceX BFR will allow the upper stage Big Falcon Spaceships to reach 9 or 10 kilometers per second. The SpaceX BFR will let us reach 80 to 90% of the asteroids.
