So, as some of you may have read I recently posted a thread about lowering the front end of my '04 636. I wanna turn it into a track day/race bike.

The other thing I was looking at doing, was going from a 180/55 rear tire to a 180/60 or 185/55 tire. The way I figure with how the aspect ratio works on tires, and more specifically bikes, is that if I increase the aspect ratio by having a slightly fatter tire on the same rim, the rear tire begins to take on more of a triangular shape. It should come to more of a point at the center of the tire. Perhaps making it harder on the tire (as well as the rider) to maintain speed in a straight line. However it should help "throw" the bike into the corners a little better.

My reasoning on this is to decrease the amount of time and effort to transfer the bikes weight to go from full lean to the left to full lean to the right.

If anyone out there is familliar with what I'm talking about, could you please tell me if I am right on my reasoning or am wrong, along with any other feedback that my pertain to the question.
