I also have the Ride Like a Pro video and practiced what it preaches.
I found that with my old HD Electra Glide, ( although never as fast or agile as the motorcycle officer in the video ) I could keep it between the cones.
With my Vic Vision, I'm not as agile, I believe it to be a combination of longer wheel base and steering head geometry.
I do agree the fellow in the Video has the best riding skills I have ever seen
