i'm 5'5", 138lbs. i'd say i'll ride semi aggressive while being a little on the safe side, as i don't feel like getting injured anymore. while i've been away from motocross, i've owned street motorcycles and race bicycles, both road and mt. bikes. i'm really wanting to spend around $1500, but not sure what are good bikes and which ones(models and years) to stay away from. for instance i know a guy who bought an 86 kawasaki(not sure about the year), but couldn't find any parts for it or something like that. i want to keep it around 2000 or better, but want to know which bikes to stay away from or definetly look into. i'd like to keep it at that price. also, am i looking at 2 stroke or 4? does it even matter anymore? i'm partial to 2 strokes because that's what i grew up on. i'd like to buy something i don't have to work on right away, but i've got enough mechanical ability to work on it if broke. like i said, which years and makes are good, which bikes have known issues. thanks for any advice.
