What would be a good kind of dirt bike to get?

well i would recommend a used crf150f or a crf230 that you can get pretty cheap and resell then you can upgrade for racing.... those are both good bikes for starting. i would gear down the 230 one tooth on the front sprocket. racing bikes and these bikes are very different. just go to a honda dealer and sit on both of them and see which fits you better but if you are still grouing maybe go with the 230
