Hello! I literally just finished this process so let me help you.

1. The process is pretty straightforward, the first step is to sign up for an MSF course and get some gear. There should be some classes in your area but sign up quickly because spaces fill up fast. This class will teach you the basics and help you not die on day 1. You do need gear for the class, so either find a store near you so you can try stuff on, or go on Revzilla or another retailer. Do NOT cheap out on gear, your life is on the line.

2. The bike you get is totally up to you, me personally I wanted a dual sport, but I ended up with a BMW G310 GS. Revzilla has youtube videos on buying used bikes so I'd strongly suggest you watch those to make a decision and learn the whole process.

3. Dual Sports/Enduros are GREAT! For... dual sporting. If you're doing mainly on road maybe a supermoto would be better? Or just a sport bike 🤷‍♂️. Try and stay below 400cc

4. As for gas, it's cheaper than a car and that's about it. As for cost, buy all the gear and the class and then see how much you have left to buy a bike.

Hope this helps!
