Question

i will be doing track an trail racing height 5'9 weight 125 age 13

Answer 1

I do ride yamaha but dude hondas run wayy longer and are more durable.

Answer 2

I agree that the CRF150R will be more durable, not because it is a Honda but because it is a 4 stroke. In my opinion neither of these bikes are right for you. You are too tall for even the expert version of the 150 and the 125 will be at a huge disadvantage compared to the 250F's you will be racing against. Also the 125 is horrible for woods racing. Get a 250F for sure.
