So, I was at Gateway HD and Buell here in 29 degree St. Louis looking at the new bikes instead of riding (yes I'm a wuss!!!). Any way, they had probably 15 Buells on the floor, including 4 new 1125cr. As I was talking to one of the salesmen, he says, "come here you gota hear this". They ordered a D&D to put on it. He starts it up and I feel like I am hearing a top fueler!!! Yes it was inside, but holy ****!!!! this thing is loud. So, if your looking for noise on your new cr or r, I can tell you, the D&D is the answer.
