That's incredibly low mileage on both, and won't make a difference in condition of the bike. Really comes down to how much time is left on the warranty on either one. If it's about color, you can always buy the other tank colors through HD. If it's truly a first strike, make sure it has the certificate to prove it. I have both colors on my two livewires, I favor the orange over the black, so striking in direct sunlight. Good luck and let us know which one you pick!
