Following analysis of tyre performance at Sepang over previous years, Bridgestone has altered its selection of rear slicks for this weekend's Malaysian MotoGP.
The symmetric medium slick remains, but this year's harder rear will be asymmetric in construction.
The hard rear will feature the same medium compound rubber on the left shoulder as the symmetric slick, but with hard compound rubber on the right side for enhanced durability in hot conditions.
Due to its location in the tropics, Sepang is the only race on the calendar where the soft compound front slick isn't supplied, with the hard and extra-hard front slicks provided to give maximum stability in the severe braking zones at this circuit.
Owing to its high ambient temperatures, the main wet tyre for the Malaysian Grand Prix will be the hard compound option and being located in the tropics, sudden wet weather is always a possibility at Sepang.
“This will be the third time this year we have visited the Sepang circuit after the winter tests at the beginning of the year and all the hard work put in by the teams and riders will be very important in establishing a setup for this weekend,” said Hiroshi Yamada, manager of Bridgestone's Motorsport Department.
“The level at which Dani [Pedrosa] and Jorge [Lorenzo] are riding right now is very high and they continue to push each other to the limits to the delight of all of us who get to see them compete.
“Sunday's race will start later in the day than usual at 4pm and there is a strong chance of rain throughout the weekend. I hope that the weather doesn't have an impact on the race and that we can enjoy a thrilling contest at this fantastic circuit.
“Of course, it will be with a heavy heart that we participate in this year's Malaysian Grand Prix as we remember Marco Simoncelli.
“I believe everyone in the paddock will be thinking of Marco throughout the weekend and will do all they can to ensure the MotoGP fans of the world are treated to a show that is worthy of his memory.”
