Is getting a motorcycle worth it?

No they are not worth it unless you believe they are.Most engines are quite worn at 18,000 miles.Being out in the open the temperature during riding is many times very uncomfortable.You are safer in a auto or pick up and more comfortable.

Bikes come in scooters, dirt, enduro, dual sports, sports, street sports, cruisers, touring.

   No pansy "standards" just like every Person is unique. That's why many build  choppers.

Yes I am Over 80 and today I want a Yahama 250 V twin 2021 in Black which should see me out

My 20 years of riding were priceless. I owned my motorcycles for enjoyment and transportation, not as investments. If you want one for an investment, shop for an Arlen Ness Custom and never ride it.

I left it after 15 years of riding. Car drivers are getting too nuts with the You tube stuff.

is it worth it? What do you mean by worth? In my day we bought panheads and knuckleheads from junk yards CHEAP because thats what we could afford and nobody else wanted them. It was cheap pretty reliable transportation. Now all makes and models arent cheap. But they are still cheaper to own and ride daily than a car. More fun most of the time anyway. That softail isnt a small light motorcycle.Not saying dont get it as your first ride . Also not saying do get it. If your a big strong guy you might have no problem. My first ride was a 71 T110 Triumph 650 triumph and it was a chopper. Narrow Z bars and a stupid choice for a first bike. But I never crashed it, In fact I still own it. I would say as other have take the MSF safety course. Find someone with a bike to go ride with until your ready to ride on your own. Take it easy just cruise along. You should be OK. 

Take the Motorcycle Safety Foundation courses in your area.

Get the training. Do not buy a bike until you have.

It is not an investment – like any vehicle it will depreciate as soon as you ride it off the forecourt.

The initial purchase is only the first cost – you will need to budget for consumables and servicing.

Most riders would advise buying a secondhand, smallish (engine capacity) bike to get some experience before buying a larger more powerful one (although there will be disagreement).

Take the beginner's course required to get your mc endorsement. Those courses have loaner bikes for the students.  If you like the class, buy a smaller (under 500 cc)  used bike to start with. You can always sell it and quit riding. Like, don't overthink this horribly complicated genius-level problem, dude.

All these months of research and you call it "driving a bike"......me smells a big bunch of hooey. One RIDES a bike, drives a car or truck and operates heavy machinery. 

Take the riding course offered MSF, Harley etc. See how it goes, see if you even have the eye/hand/foot/ coordination necessary. Ask the instructors for motorcycle recommendations for your skill level or lack thereof - they will be honest. Start small, get all the stupid mistakes out of the way AND see if you really like riding enough and are comfortable enough to move up to a bigger bike after about 5k miles. "The motorcycle you currently own is just the one before your next motorcycle" It is a progression of learning your comfort levels, distances you are willing to ride (touring vs bar to bar hoping are quite different requirements).
