Hey guys recently my rm85 has decided to give up on me and the throttle was stuck at full speed so I broke a few bones. So my dad is pushing me to get a new bike. Before the incident We had brought the rm 85 to be repaired but apparently it didn't do much. Anyway I was wondering what would be a good trail bike for me. At the moment I am almost 15 and am 5'10. I have been riding for only a year so a 125 two stroke is out of the question according to my dad. I was wondering if a crf 150r would be a good choice for me. But I do want a bike I won't grow out of within 6 months. Would the crf 150 be a good choice? And what's the difference between a crf 150r and crf 150f? Thanks
