I am looking to pick up my first bike. I am 5'11 160lbs 18years old, got about 3 more inches to grow at most and i have no previous motorcycle experience. I want a bike that isnt to powerful that i wont be able to learn on it, but i dont want to get a good learning bike then get tired of it because it is too underpowered. I have $5000 to spend and 2 stroke or 4 stroke doesnt matter and i have no brand preferences. I think i will be doing about 80% trails and 20% track with no racing. All opinons are appreciated!
