If you want to get a bike, get a bike but don't kid yourself into thinking you'll save money. Most likely you won't.
By the time you factor in the cost to purchase, training, insurance, and equipment, it's very unlikely that you'll save much, if any money. Also consider that motorcycle tires typically cost about $75-$150 each (depending on what type of bike and tire) and for installation you can figure another $50-$60 or so.
Who pays to have thier tires changed? LOLz. Also MC tires wear out about 5 -8 times faster than car tires (I've been riding 30 years and I can count on 1 hand the number of times I've gotten 10,000 miles on a tire. Actually, I can count on one finger. (6,000 -8000 miles is typically what I get from a rear tire, fronts can last about 9,000.)
I replace tires every 2000 miles whether they need it or not. I allways run the stickiest compound so that I put fresh new tires on my bikes every spring. No dry rot or hard tires for me. the extra cost is worth it. Deosn't matter if it's a sportbike, ADV bike, or dual sport. Run the good tires. Most motorcycles need valve adjustments every 12,000 miles or so and that's a few hundred bucks unless you can do it yourself.
I check valve lash myself often. I have my Honda tech adjust them when the lash gets tight. But, never, ever take a bike in for a valve adjustment if it really deosn't need one unless we're talking 16,000 miles or something obvious. Easy money for them.
Finally, you will find that a motorcycle is not that convenient. If it's raining, if you have a passenger to carry, if you need to stop and get groceries, if it's unseasonably cold, then you may find yourself driving the SUV and leaving the bike at home.
He's in GA! Bikes have thier conveniences as well. They fit in elevators easy. And glide right through the front door of the apartment I had in Gainesville.
If all you need is cheap transportation, a 10 year old compact car with 125,000 miles on it and a manual transmission will save you more money than a bike ever will.
Not trying to dissuade you from getting a motorcycle, just saying that the "it will save me money" argument rarely works.
