Not so.
Top speed is limited by aerodynamic drag and BHP. To go faster you need
less drag or more bhp or both.
Acceleration on the other hand is limited by lb/f torque to weight ratio (to
the point where the drag is greater than bhp and limits top speed and
therein acceleration).
The motorcycle has less drag than a car (less frontal area really) so needs
less bhp to reach its maximum speed. The wheel diameter is neither here nor
their because the gearing controls the gearing and the wheel diameter is just
one factor.

Fact
is, BHP or HP by any measure really has nothing to do with speed. Only in
elapsed time to reach a given speed. I have seen a 20 HP motorcycle reach
110 mph because of its wheel diameter and gearing. Likewise, I have seen 200
HP V-8s that couldn't hit 90 MPH.
Cheers!!
