almost all Harley dealers have a riders edge course, That is a good beginning.
It is a sales tool for many of them, don't fall for it on a first bike.
Gear. Get good armored jacket and pants, good boots, good gloves, full face helmet. That will cost over 1000, could be 1500. White helmets very visible. Even with insurance, one trip to the emergency room is usually more. 40% of crashes you land on your face, I recommend only full face helmets, or flip front helmets. there are utube training video. The training and gear will add 2000 to the cost.
You engine is used for braking as well as accelerating, It is one of your 5 basic controls on a bike. Automatic diminishes that to some degree.
Foot peg weighting in another control, don't throw that away with feet forward controls.
Best to buy a bike with ABS brakes, regardless of what the haters say, it is really better. Hit wet leaves, becomes non event. Spot of oil, non event.
Learn how to pick up the bike without hurting you. Utube again.
