"In the beginning there were 3 or 4 rubber compounds. At first we were physicists, but then we became chemists because we were getting our butts kicked," said Pierre Dupasquier, Michelin's former director of competition.

Pilot^® Power tires were the first to benefit from these new synthetic compounds, scarcely two years after they were introduced in GP racing. Or as the advertising campaign put it, "Pilot^® Power: With 100% Pure Racing Ingredients." Fitted with Pilot^® Power tires, a sportbike can achieve a remarkable lean angle of 50.6 degrees – 3.6 degrees more than its predecessor, Pilot^® Sport. At the time, it set a new benchmark for road tires.
