When you are traveling and such high rates of speed you don't dare look down at the speedometer. It's nice when you have a passenger that can look for you. I didn't believe my wife when she first said it, over 140 mph at the end of the straight. In this video the angle of the sun was just right and you could see the speedo - I think she was right! The cp-e performance parts really make The Black Knight a step above the rest!
