Take the Motorcycle Safety Foundation beginners course first, before choosing a bike. Around here, they give you a 250cc Suzuki standard bike to use. A standard bike has the footpegs below the seat, easiest for a beginner.
So Harley Davidson lovers will not tease you, it is best to ride either a sportbike like the 250cc Kawasaki Ninja, or a dirt bike like a 250cc Kawasaki or 400cc Suzuki supermoto. They tend to like the Triumph bikes or the 500cc Kawasaki Vulcan cruiser better, because they have a parallel twin engine instead of a V-twin engine that copies the Harley look.
I have the worst bike for a Harley lover- a Honda cruiser with a V-twin engine that is a smaller copy of a 1985 Harley Softail, but with a 1950s English V-twin Shadow name. I have never had a Harley rider make fun of me- they tend to not look at me or my bike, and do not talk to me, like I do not exist. I ride with some guys with Harleys- once in a while they will ask when I am going to spend more to get a real bike like a Harley big twin.
