Hey out there, I am looking for some imput! I am currently riding an uncorked XR400. I am looking to replace it with something alot lighter and faster. I usually ride in the So Cal mountains and in when I get time I head out to Laughlin NV. Do you think that the CRF450 is going to be too much bike for single track riding? I know it will fair well in the Nevada desert. Any comments or suggestion would be greatly appreciated. Also, how many miles can you get out of one tank of gas? I currently am getting 80-100 miles out of one tank. Thanks in advance.
