Bridgestone slick compounds available: Front: Soft, Medium, Hard. Rear (asymmetric): Hard, Extra Hard
MotoGP travels to the United States of America for the second time this season for the Indianapolis Grand Prix on 28 August, round 12 of the 18-race series.
The inaugural Indianapolis Grand Prix was only held in 2008 but for this year’s Grand Prix 1.5miles of the 2.6mile circuit has been resurfaced so half the circuit is new, posing a new challenge for Bridgestone’s tyres.
The Indianapolis Motor Speedway, affectionately known as the Brickyard, is formed of three distinct parts; the famous oval, the infield road circuit built for Formula One in 1999, and the opening complex built specifically for MotoGP. Whereas in past years each section of the circuit has a markedly different surface which offered a different level of grip, now initial feedback indicates that the resurfacing work has made the grip level much more consistent and the tarmac much smoother, which will help the riders and also the tyres as bumps interrupt the rubber’s contact patch.
In theory this will make it easier on the tyres as previously the multitude of different surfaces in a lap demanded a lot from them but the surface is also brand new so a relative unknown, although Nicky Hayden did test the new surface after the last American round at Laguna Seca and his feedback was very positive.
Nevertheless Bridgestone’s tyre compound selections are unchanged this season, although with the addition of the third softer front slick option to maximise warm-up performance and rider safety in conditions that are colder than expected.
The circuit’s layout places much higher demands on the left shoulders of the tyres and in fact it is one of the hardest circuits of the season for the left shoulders of the rear tyres because of the number, length and speed of the left-handers and the abrasiveness of the tarmac. For this reason it is the only Grand Prix this season to which the extra hard compound rear slicks have been selected, although both rear tyre options feature Bridgestone’s soft compound rubber in the right shoulders.
Hiroshi Yamada – Manager, Bridgestone Motorsport Department
“This week we’re back in America again, now in the east in Indianapolis as opposed to last time we were there five weeks ago at Laguna Seca on the west coast. It’s clear that Indianapolis are working hard for the benefit of MotoGP with all their recent resurfacing work and we are happy to be going again to such an historic circuit. Indy is a vast place so I hope that we can see many spectators in the huge grandstands! Even though Casey’s win last time out extended his championship lead over Jorge, we’ve only just started the second half of the season and there’s a long way to go until the title is decided so I fully expect to see the championship fight really gathering pace in Indy and the remaining six grands prix.”
Hirohide Hamashima – Assistant to Director, Motorsport Tyre Development Division
“Reports are that IMS have done a great job resurfacing the circuit which will make for more consistent conditions this year. It won’t change the physical demands placed on our tyres, because the corners are still the same and haven’t been re-profiled, so we haven’t changed our compound selection from last year other than with the addition of the third spec of front tyre with the new regulations. The speed may be a little higher because the tarmac and the grip will be more consistent, whereas in the past there were clear changes in the circuit character from the opening section designed for MotoGP to the Formula One infield to the famous oval. The tarmac is much smoother now which will also help as bumps interrupt the tyres’ contact patch and we saw a few falls last year because of this.
“Indianapolis is a relatively hard circuit for the left shoulders of our rear tyres in particular because of the speed and long nature of left-handed corners such as turn one and turn five. Being leant over for a relatively long time at speed creates some of the highest rear tyre temperatures of the year, and for this reason Indianapolis is the only Grand Prix all year for which we have selected the extra hard compound rubber in the left side of the rear slick tyres.”
Dunlop heads to America’s most-famed motor racing location for the Red Bull Indianapolis Grand Prix on August 26-28, the eleventh round of the 2011 Moto2 Championship.
Indianapolis – world renowned for the Indianapolis 500 Indycar race – features an anti-clockwise circuit made up of sections of the banked oval track combined with an infield section.
Despite its fame for four wheeled motorsport, Indianapolis also has a strong two wheel history, with the first motorsport race taking part at the venue being a motorcycle race in 1909.
MotoGP has raced at the circuit since 2008, and the banked turns and the potential high track temperatures in which they can bake provides a rear test for the tyre manufacturer’s art.
Dunlop will bring the front tyre allocation of the 717 hard compound which has been used at all round so far this year, and the slightly harder medium compound of the 302, which replaced the 753 medium from the Sachsenring round onwards.
In response to the circuit’s characteristics, Dunlop will bring the dual compound W919 rear tyre as well as the 3868 compound.
Ten left-hand corners and six right-handers mean more work for the left hand side of the tyre, so the W919 features a harder compound on the left and softer compound on the right – allowing riders to enjoy the best of both worlds: Long-lasting endurance on the frequently-used left, plus instant grip on the lesser used right.
“This year, we will have available the same two compound fronts (302 and 717), due to both being race options last year,” explains Dunlop Motorsport’s Moto2 co-ordinator, Clinton Howe.
“The rear options have changed since last year and we have gone from the 6868 and 6838 compound options to the W919 dual and 3868. We hope these will improve on last year’s rear tyre performance.
“Last year we saw very high track temperatures which had a detrimental effect on the rear tyres’ grip levels, however tyre wear and consistency were very good with race winner Toni Elias setting his best time on the last lap of the race.
“The track surface was different in three parts which made bike set up critical, especially with some banking in some corners and negative camber in others.
“We have the added excitement of a new track surface from turn 5 to turn 11 this year, so it is a little bit of an unknown. Feedback from riders who have tested already on the new surface is that it’s very abrasive compared to last year.”
The Indianapolis round of the Moto2 world championships starts with practice on Friday 26 August, followed by qualifying on Saturday and then the race at 12:15 local time on Sunday.
