Lorenzo Sets Records on Asymmetric Rear at MotoGP US Round

Jorge Lorenzo rode his Fiat Yamaha to a new fastest race time in Round 9 of the 2010 MotoGP Championship on Sunday, tearing around the United States’ Race Mazda Raceway Laguna Seca, furthering his lead and seemingly inexorable rise to this season’s title. Tyre supplier Bridgestone was quick to explain the advantage its hard front and softer asymmetric rear slicks had given the field: every rider favoured the softer option asymmetric rear slick tyre which featured the improved medium compound rubber to offer better warm-up performance. “Its increased level of performance at higher temperatures was the reason it was sufficiently durable for race distance even as the track temperature reached 44 degrees,” a Bridgestone statement read.
