This is my 2008 yz250f special edition i just got today. This is my first dirtbike and i had to trade in both my yfz450s, the atv's, for this bike. I have heard that before that u go riding for the first time u have to do something with the spokes. Is this true? Other than break in the motor what else do i have to do for my first ride?" This is my first dirtbike and i have had quads all my life so is there anything special i have to do for the forks and other dirtbike parts? I have just ridden it up the driveway so i cant tell u how it performs but tomorrow i am going for a ride so i will give u guys a full ride report. I did not know that the yz250f came with Excel rims.
