if u dont already have a car driver license, and u just get a full motorcycle license (no permit), u cant legally drive dad’s car until u get a regular driver’s license.

now u need to choose the type of bike. sport, sport-touring, or cruiser. sport-tourer’s is a bit of a hybrid; has the looks of a sport bike, but can give the comfort of a cruiser.
if a sport bike is ur choice, and u are a 100% rookie with zero miles on the saddle, 9 out of 10 rider’s will suggest getting a kawasaki ninja 250.
cruisers, u could go with either metric or harley. the 883 and 1200 sportsters are mid-sized but are ‘small’ compared to other harley’s.
if u prefer a cruiser, and would rather get a harley, u wouldnt go wrong with getting either a sportster, or even a wide glide.

its highly suggested u take the basic rider course. before u hit the road. some states will waive the on-cycle test requirement to get the full endorsement if u pass the brc.
