I have rode a friend of mines crf100f and really enjoyed riding it.now my step father wants to buy me bike. I'm a girl I'm 5'6" and I way about 120lbs should I stick to a bike like this or what. I don't really want a bike that I wouldn't be able to pick up if I fell. the bike I rode is actualy a friends brothers and we are both intrested in riding seriously. the crf100f is now my friends. we will probably trail ride and are thinking about racing once are skill level gets up. so what do you guys think would work for me
