Pirelli is back in action on Friday at the fascinating American circuit of Laguna Seca with the riders of the eni FIM Superbike World Championship for the ninth round on the calendar. It will provide riders with standard SC1 and SC2 flanked by the development S1699 tyre as solutions for the front. For the rear; standard SC0 and SC1 for all with the addition of the R1368 for the EVO riders and the T384 only for the Superbike class. For Superpole the new T0223 tyre which debuted with successfully at Misano is back. The Laguna Seca round is an event involving only the premier class riders and is the last before the summer break, which will last until 5-7 September, when all classes return to race at Jerez de la Frontera, Spain. With five rounds to go, Tom Sykes (Kawasaki Racing Team), who this year has already taken three doubles by winning both races at Aragón, Misano and Donington, leads the overall standings with 284 points. He has a lead of 43 points over his closest pursuer Sylvain Guintoli (Aprilia Racing Team) who, since the beginning of the season, has achieved two first places, one in Australia and the other in Assen. Not very far from them are Loris Baz (236 points) andJonathan Rea (Pata Honda World Superbike Team, 235 points). Marco Melandri (Aprilia Racing Team), fifth in the league, has a tally of 192 points. Laguna Seca VS tyres: the "Corkscrew" stresses the front tyre and affects the grip of the rear tyre Mazda Raceway Laguna Seca is a 3610 (2.243 miles) metre long and 15 metre wide circuit with 7 left-hand curves and 4 right. The rider in pole position starts on the right hand side. The longest straight which measures 453 metres (0.281 miles), and the track runs counter-clockwise. The track was built in 1957 on the side of a hill 250 metres above sea level. In 1988 it achieved the minimum length required by the FIM rules, due to the construction of a new section between turns 2 and 5. The layout of Laguna Seca makes overtaking difficult due to relatively few points where it is possible to ‘attack’.

Laguna Seca is perhaps the most interesting circuit in the United States because of its configuration with massive elevation change and fast sections alternating with slower corners. Usually on Friday the track looks dirty because of the presence of sand but there is another strange phenomena: fog which arises in the early hours of the morning. A time in which the temperature can be several degrees lower than in the afternoon because of the location of the circuit; on a hill not far from the sea. That's why in addition to solutions in soft compound for the rear which are suitable for high temperatures, Pirelli also brings the SC1, offering most protection in the event of lower degrees. In the famous section named the "Corkscrew" (Turn 8 and 8A), a very spectacular chicane situated on top of the hill runs down a very steep slope. Riders cover with a speed of around 80 kph, seeing rapid counterslope changes of direction that stress the front tyre and, at the same time, the load transfer can affect the grip of the rear tyre. The start-finish straight is very short, with two slight changes of direction where the maximum speed is reached, equal to 270 kph for Superbikes, is another challenging point. Finally, the righthand turns 3 and 4 allow a good lap time, which is why it is very important that the tyres have excellent grip performance even on these slow corners of approximately ninety degree angles. Pirelli solutions for the Superbike class: To Laguna Seca Pirelli comes with a load of 1939 tyres to meet the needs of the riders of the premier class of the Championship. Each rider can choose from 30 front and 38 rear tyres including, in addition to the dry tyres, also intermediate DIABLO™ Wet and DIABLO™ Rain tyres. Regarding slick tyres, there are three solutions provided at the front and the same quantity for the rear. For the front Pirelli, in addition to the standard SC1 and SC2 respectively in medium-soft and medium-hard compounds, arrives a third and final option; the well-known S1699, which debuted successfully at Aragón offering more support in the approach to the corner in favour of better steering precision, qualities that have made it the choice of the majority of riders at Assen, Imola, Donington, Misano and Portimao. At the rear, the standard SC0 and SC1 and then a solution dedicated to each class: Superbike riders can rely on the T384 solution, a development tyre in soft compound only brought so far to Imola tests and Portimão. The standard solution should provide excellent grip even with very high temperatures. EVO riders can exclusively use the R1368, a development solution that uses a very soft compound offering a lot of grip when used in high temperatures, up to this point has been brought only to Misano and Imola.
