Superbikeplanet.com (or Soup, as it is known in the vernacular) has a great set of comparison images of the Michelin tires at the end of the Laguna Seca race. What is really obvious is that the Yamaha uses its rear a lot harder than the Honda does. Either they have traction control working better, or they have a smoother torque curve. Well worth a look.
You can find the images here.
