I will be turning 15 this month. I have been riding an XR400 for about 4 days now and can handle it well but was wanting something a little more modern like an mx crossover bike. I have been riding a CRF150F for 2 years. I will be riding trails and plenty of open fire lanes. I am 5'6" and weigh 115 lbs. I know they have about the same horsepower. I also know that there is more aftermarket support for the wr. The XR costs $3200 and its a 2002 model and is in great shape. I am not sure about getting a wr. Any help would be appreciated.
