The decreasing-circumference curve

In July of 2007 I nearly killed myself. I didn’t do it intentionally, but I almost died from a terminal case of poor visualization.

That’s right, poor visualization almost ended my life.

The motorcycle is a beautiful machine. In motion it is graceful, yet it defies the physical senses. When a motorcycle carves through a corner it solves a ridiculously complex equation involving speed, the rider, the road, the tires and a thousand other elements that allow the motorcyclist and motorcycle to lean into the corner at an angle that appears — in video or photographs — perfectly impossible. Until the rider gets used to it, it doesn’t feel any more plausible than it looks.

The decreasing-circumference curve is the bane of the inexperienced rider. In the mountains, curves are not always symmetrical. If you enter a turn with a gentle arc and that arc gradually becomes smaller, then you are in a decreasing-circumference curve. This presents a serious problem when you enter the corner too fast and then discover it closing down on you. It’s your classic rookie error, and I made it.

There’s only one way out and slowing down is not an option. To brake a motorcycle in a high-speed corner is disastrous. You’ll lose traction and lay the machine down on its side. So the experienced rider leans deeper into the irrational angle and holds his intent. He visualizes a successful outcome. He experiences the exhilaration of successfully testing his own courage and skill against the laws of nature.

I, on the other hand, lost my nerve. Rather than visualizing myself – and the motorcycle – carving our way out of our predicament I became trapped in a tentative state of mind in the middle of the turn. I let fear take over. Even though I was following two other riders who had successfully negotiated the corner, even though logic dictated that I could follow those other riders, I lost my confidence. I just couldn’t see myself completing that turn at that speed. I couldn’t visualize it and, for lack of a clear mental picture, I became trapped in the curve. Instinctively, I tried to slow the motorcycle down. In an automobile that would have been precisely the right answer. On the motorcycle it was a bad decision and could have been disastrous. The motorcycle and I went sideways, bounced off a fortuitous guardrail and I went down in the middle of the road at about 45 miles per hour.
