This is kind of screaming Honda CRF300LS. Low seat, it’s super easy to ride, great learners bike. Throw a set of wrap around handguards on there when you buy it, and you can drop it all day without really much consequence. They aren’t all that expensive, and pretty low maintenance. Dual sports make great learning bikes too, they are super approachable, let you make all the mistakes with lower consequences, and you can literally take that bike just about anywhere. It’ll do 55mph no prob, I’m pretty sure you can get those things going 70-80mph. They ain’t built for highway comfort, but they make a great around town bike. You can even get a little rack for the back.
Take a course, it’s invaluable, especially when you are learning. Otherwise you’ll spend the first year struggling.
The bottom paragraph especially. It’s a terrible idea honestly. It’s better to learn how the bike should run, and what to watch for, before you need to actually watch for it and wrestle with it.
