Welcome.
If you haven't already done so, you should enroll in a Basic Riders Course. This is typically run over a weekend, with classroom discussion on a Friday evening, followed by two full days riding in an closed parking lot. Everyone starts from zero. Successful completion earns a certificate good in most states for the riding portion of the motorcycle license test, leaving only a simple written test to obtain the motorcycle endorsement on one's driver's license.
The Rocket is generally considered a graduate bike, as it is unforgiving of the momentary inattention when stopped most new riders experience. The bike departs from vertical, and not caught immediately, it goes down, and is hard to re-right. It is also near impossible to back up any incline, meaning one must always consider one's heading when parking.
The right physique combined with a positive attitude, and love of learning, could be ok.
Nothing beats real road experience.
Good luck.
