This is life at the races. Because everything on motorcycles is tightly interrelated, you can’t change just one aspect of performance without unwanted side effects. When Dorna asked spec-tire supplier Bridgestone more than a year ago to improve tire warm-up in the first three laps of races, the result seemed to favor Marquez’s modified dirt-track style and slightly reduced the edge grip essential to Yamaha’s corner-speed riders. This places less value on traditional performance variables, such as power, range, and suspension, and magnifies the importance of how fast a factory can respond to changes in tires or rules. How many new, yet subtly different, chassis can your organization design, build, and test per unit time?
