Bridgestone MotoGP Race Preview - Indianapolis

The second of two races taking place on American soil this season will be held this Sunday at one of the most revered motorsport venues in the world, the legendary Indianapolis Motor Speedway, whose distinctive layout places significant demands on Bridgestone MotoGP tyres.
The Indianapolis circuit comprises three distinct parts; the renowned oval which forms the main straight, the opening complex and turns seven and eight built specifically for MotoGP, and the rest of the infield which was constructed for when the circuit held Formula One races. Large sections of the circuit were resurfaced last year, resulting in more consistent grip levels, while some undulations on the tarmac that caused the bikes to behave erratically in corners were also removed.
After revising its tyre severity ratings for each circuit, Bridgestone will now supply special construction asymmetric rear slick tyres in the medium and hard compounds at Indianapolis to manage the very high tyre temperatures the 1000cc MotoGP machines are expected to generate around this circuit. The circuit’s abrasive tarmac and counter-clockwise layout with its fast and frequent left handers makes it one of the hardest events of the season for the left shoulder of the rear tyres; hence asymmetric rear tyres with considerably harder rubber on the left shoulders are supplied. The abrasive Indy track also means the extra-hard compound front slick is included in the tyre allocation alongside the soft and medium compounds.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“It is always a pleasure to visit Indianapolis as the motorsport culture here is very strong and the whole city gets behind the Grand Prix with many events taking place over the weekend. The venue itself is quite unique with elements of three different eras incorporated into the circuit and it is a challenge for both riders and tyres. Perhaps due to its particular layout, Indy is a race where the result is always hard to predict with four different winners and seven different riders making the podium since the race was included on the calendar four years ago.
“Apart from the regular MotoGP roster there will be two extra riders in action at Indy. Steve Rapp will once again be riding the Attack Performance-Kawasaki CRT entry, while Aaron Yates will debut the GPTech-Suzuki CRT machine so I expect even greater interest in this race from the American fans this weekend. To give these wildcard riders the best possible preparation for the coming weekend, our race engineers were on hand to assist both teams in a test at the Indianapolis circuit that took place on Saturday.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
“This year we have revised our rear tyre compounds for Indy and have gone one step softer with both options, with the medium and hard asymmetric rear slicks being supplied. Additionally, the rear slicks for this circuit now feature the same special heat-resistant construction as those provided at Mugello, Sachsenring and Phillip Island. Our compound selection for the front slick tyres also changes this year, with the soft, medium and extra-hard options now being made available to provide riders with a front tyre option for every kind of track condition.”
