Actually it's the perfect size for you. I'm 6'3 180 pounds and my gf has a crf 150 and it's good great power to pull me around, she upgraded to that from a crf 100 when she got really good and was able to handle it because she's small, it's still to tall for her but she can handle it. Really nice bikes and TONS of upgrades for them if you get good and want even more power. They are the best beginner to entry level rider bike I've ever seen. When you get older and a lot better down the road maybe in a couple years you can easily upgrade to a 250f or bigger, these 150's are very nice though.
