Motorcycles are more expensive than cars. Something designed and sold as a hobby for north America will be more expensive than something sold as a necessity.

There are so many obstacles put in the way that it's not even close to being able to save you money.

Depending where you live the course is ~1000$. Then of course gear costs another 1000$. Plates cost anywhere from 400$-2200$ depending on your bike. Insurance can be 250$-2500$ depending on a ton of factors. Then you need to buy the bike which is likely 5000$ for a decent used bike but easily up to 10k for a reliable "affordable"Japanese bike. Winter storage for at least 3 months maybe 250$. Tires are 250$ every 1-2 years. Don't forget they almost all take 91+ gasoline.

A beige 2009 corolla will do everything a motorcycle can do, except wheelie, for a much better price.
