I am 5'2", and have been riding a xr200 on relatively flat terrain. I am able to pick it up off the ground 200+ lbs. I am soon to be riding tight mountain trails. I am contemplating either buying a crf150 or a crf230. The 150 feels very comfortable, but the 230 will have more power. My worries are being able to manuever the 230 up in the mountains at my height and the bikes weight of 238 dry weight. What should I buy?
