Bridgestone slick compounds available: Front: Soft, Medium. Rear: Medium-Soft, Medium (Asymmetric)
Bridgestone wet tyre compounds available: Hard (Main), Soft (Alternative)
Round seven of the 2012 MotoGP™ World Championship, the Dutch TT takes place at the historic Assen circuit which despite having one of the shortest straights of any circuit in the series, has the second fastest average speed.
Assen is not particularly demanding for front tyres even though grip levels on the circuit are quite variable following a partial resurfacing in 2006, so the soft and medium compounds are offered to provide better grip and warm-up performance. The rear tyres are put under comparatively more stress and in particular, the sequence of right-handers from Mandeveen to Hoge Heide generates significant load on the right shoulder of the rear tyre.
Although cool track conditions are common at Assen, warmer temperatures are not unheard of. For example in 2010, the track temperature during the race reached 47°C compared to a peak of just 18°C in 2011 and this potential for large variations in track temperature makes developing tyres for Assen a challenge and emphasises the importance of the wider operating temperature range engineered into the 2012 specification MotoGP™ tyres.
To meet this challenge, Bridgestone has revised the compounds in its asymmetric rear slicks for Assen with last year’s medium and hard options being replaced with the medium-soft and medium options. These new rear slicks feature either the extra-soft or soft rubber on the left shoulder combined with the medium compound rubber on the right shoulder to keep the tyre in its optimal temperature range and to provide greater edge grip from the first lap.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“The Dutch TT is one of the highlights of the MotoGP season and the fast layout of the Assen circuit requires maximum commitment from racers. This weekend marks the start of a very busy time for the paddock and over the next few weeks fans will be treated to back-to-back races at three amazing venues. It is always hard to predict what the weather will do at Assen, but I am confident that our revised tyre selection for this race weekend is well matched to the demands of this technical circuit.
“Jorge is looking strong at the moment after his three successive wins, but Casey, Dani and Ben, who had a fantastic victory here last year, will be very motivated to end his winning streak and so I believe another intense contest will take place on Saturday. I hope that both Cal and Karel are making progress in recovering from their injuries and I look forward to seeing them back in action soon.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
“Assen is one of the faster circuits on the calendar and requires asymmetric rear tyres because of the high loads placed on the right shoulder of the rear tyre in the fast right-hand corners. Following some alterations made to the circuit in 2006 there are two distinct types of tarmac: the new part is slippery whilst the old is abrasive, which creates variable grip levels and makes it particularly tricky for riders in the wet.
“In a similar development to Silverstone, to address the generally cool temperatures encountered at Assen we have changed the selection of asymmetric rear tyres for this weekend to the medium-soft and medium compounds. As the tyres at this circuit have to cope with a wide range of corners from very slow to high speed, shoulder grip is crucial hence us selecting rubber compounds that are relatively softer than at other circuits.”
Dunlop heads to Assen with new pairing
Dunlop’s Moto2 tyres head to the only location to have been on the MotoGP calendar since its beginnings in 1949; Assen in the Netherlands for the seventh round of the Moto2 World Championship – the Iveco TT Assen – on June 28-30.
Flats and Camber
The Assen location offers an interesting challenge. Its flat location, around 60km from the coast often delivers wet or cooler conditions. In contrast to the surrounding countryside, the track layout itself makes significant use of cambered corners to add a different element for the riders and tyre engineers to consider.
For 2012, Dunlop will bring a new allocation pairing of the 3854 soft and the 3855 medium rear compounds. This is the first time that this selection has been combined for an event and its selection follows favourable feedback for the newer 3855 compound which was used at Qatar and Silverstone.
3854 is the softer option core compound, offering very consistent performance and usable at many circuits as a soft or hard option, depending on circuit severity. For Assen, it acts as the softer tyre allocation. 3855 is a new compound for this season in Moto2 which was debuted successfully in Qatar at the season opener, and used subsequently at Silverstone. The season-familiar front allocation of the 717 and 302 compounds will join their rear brethren.
Dunlop’s Moto2 Operations Manager, Clinton Howe:
“You need a tyre with good stability for Assen. It is both a tight and technical track but it is also fast and flowing. The changes in recent years to the first corners have altered the feeling of the circuit so that the tyres are worked more on their right side now, as the first corners are four parts of a continuous arc. We do see high abrasion from the circuit surface in cool conditions, and flat surroundings of the location lend themselves to cooler temperatures. On the track itself however, there is a lot of positive camber in the turns. This assists with cornering speeds and also the flow of the track. When it’s wet it also assists with water drainage. It’s not a small amount of angle to the corners either, it seems like there’s as much camber as a NASCAR track in places!”
Moto2: Toni Elias, Mapfre Aspar Team:
“Assen is one of my favourite tracks. It is very fast and it has many corners with banking which makes things interesting. I would have to say that I preferred the old circuit, but the current version does have a good style. It is really fast, and the variety of corners is interesting. Some are flat, some have banking, so it is always changing between the two. The weather is also a factor, as it’s often either cold or wet. Dunlop’s tyres do give me good confidence. They have to be able to deliver their performance straight away, especially at a track like Assen. Good warm-up is important and I don’t have any problems at all with the Dunlop tyres delivering this.”
Moto2: Xavier Simeon, Tech 3 Racing:
“The Assen track is mixture of slow and fast corners, a track with lots of double corners. Last year was a good race for me, until I crashed. This year I am hoping that it will be better for me even though my hand is still injured, but the Silverstone race proved that I can do okay with it like it is. I am hoping for a good race in Assen as it is near to my home and I would like to please my fans. Over the last two years Dunlop’s tyres have improved and are more constant throughout the race. This means a rider has good confidence to make good lap time towards the last laps of the race. I saw this in Silverstone and hope for the same in Assen.”
