The 150r is a race bike, and if you were racing then yes thats a really good bike. You will have to know how to maintain a 150r because if you dont and you let it get messed up, it costs allot to get it fixed. The 150f is a trail bike and is about the same height as the 150r but is heavier and is made for trail riding. The 150f is bulletproof and there is barely any maintainence except cleaning, oil changes, cleaning air filter, and make sure your chain is lubed. It really matters how you will be riding because if you get a 150f, you can usually get used to the power really quickly. I regret getting mine because i want the 150r now. But its a really good trail bike and it is really easy to use for a beginner. you about my size, im 14 and about your height, a little less weight but yes the crf-150r is a really good bike. Also, if you are in a dumb neighborhood with pissy neighbors that call on you, the 150r is a loud bike. Hope you make a good choice!
