KATHY RIDES BOSS HOSS:
It was a guided ride and I wanted to be last in line. When we down the entrance ramp to the expressway, I stayed back as I wanted to snap that throttle. I couldn't believe how fast that bike was. I was a grinnin from ear to ear. When I returned home I looked up the 1/4 mile stats to see it was about the same as a Busa. Now I see the set-up Roadsters are about that fast also. And I bought a "slow" touring.
