I have read a lot of articles on both and was trying really hard to find the answer with backed up proof. Now I don't want to see well the Harley is, does anyone have and articles that state the winner. I have seen a popular mechanics where the M109r was faster than a Night Rod Special but it said it also had an 1130cc motor. I thought the Night Rod Special always had a 1250cc... So is it faster than the 1250cc motors?
