Hi. I've recently been hooked on motorcycles. I'd love to get one and start riding and working on one. There are a few problems. First off, I'm only 13 years old, but I'm 5'11" and 160 lbs. I know that it's illegal for me to ride a motorcycle, and I'm not even sure if I can take a mfs course at this age. I wouldn't be riding on any big roads, and would barely even ride it, besides riding it to my best friends house (he'd help me work on it, his dad is into bikes, and he only lives a few miles away), and around a few back roads in my neighborhood. My dad has been riding motorcycles for before I was born, and has multiple types and sizes of bikes (he has a touring Harvey, I believe it's a VRSC, a ninja 600, and a dirt bike which I don't know the model of). He could teach me and show me how to properly ride a motorcycle. Also, I don't know what kind of bike to get. I've heard dual purpose bikes are good for starters, but I really have no idea where to start. I'd appreciate input. Preferably it'd be a bike that I could work on and modify/upgrade as I go along. Thirdly, is price. I don't really know my exact budget, but it'd be around $600-$700. I know it's barely anything, but I'd have to pay for the bike myself, and that's all I have. If it's even possible to purchase a bike at this price point, it doesn't even have to run, I'd love your input. Ideally I'd like to keep everything to the absolute bare minimum, as cheap as possible. My dad already has safety gear, and I could borrow it if I rode my bike. Again, thanks for your input, and any and all suggestions will be greatly appreciated.
