That is correct.
The physics, disregarding small factors like rolling resistance at top speed:
Assuming the following:
- 2.17m² frontal area
- 0.31m² drag coefficient
- 1.219kg³ air density
- Optimal gearing
- Flat surface
... you could achieve a theoretical 190.58mph
If you have other figures you'd want me to throw in there, I'd be happy to do it. The math is really straight forward, I just coded a simple program to handle it for me to avoid manual-data entry.
