Longueur: 5.403 m. / 3,357 miles
Virages à gauche: 6
Virages à droite: 8
Ligne droite: 636 m. / 0,395 miles
Remarque: piste assez abrasive avec un fort dénivelé (73 m) et pas de grande ligne droite.
En descente (T2), le train avant est très chargé (bon pour compenser les faiblesses des Ducati) mais c'est l"inverse en montée (T4) (par contre, c'est bon pour Elias) :)
La piste est large ce qui permet (et demande) une bonne vitesse de passage en courbe.
Malgré la montée (depuis le virage 10 jusqu'à l'arrivée), ce n'est donc pas ce que l'on appelle un "circuit de moteurs".

Round twelve of the 2012 MotoGP™ season sees the championship head to the Czech Republic and the idyllic Automotodrom Brno, a fast circuit with striking elevation changes that is splayed across wooded hillsides.
Brno’s layout features a series of straight sections broken up by a series of technical corners including four left-right corner combinations and the difference in elevation between the highest and lowest part of the circuit is almost 75 metres. As a result, the challenging downhill braking sections require front tyres with excellent stability, while superior rear grip is vital to provide good drive onto the straight parts of the circuit. Adding to the technical complexity of this circuit for tyres is the abrasive tarmac which demands high levels of durability.
There are a total of eight right-hand and six left-hand corners and though asymmetric rear slicks are provided at Brno, the loads imposed across the left, centre and right of the rear tyre are fairly similar at this circuit. The rear tyre options supplied at Brno are the medium and hard option asymmetric rear slicks, though the difference in rubber hardness between the left and right shoulders is not as great as at other circuits such as Indianapolis. Front slick options for the Czech Grand Prix are the soft, medium and extra-hard compounds.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“The Brno circuit is one of the most impressive venues that MotoGP visits, both because of its forest setting and the wide, flowing nature of the circuit. Interestingly, the rider who has won at Brno for the last five years has gone on to win the MotoGP title and this reflects the Czech Republic Grand Prix’s importance in the fight for the world championship. Also, the Czech Republic Grand Prix for the last few years has had the highest number of race day spectators on the entire calendar, with 155,000 fans flocking to the circuit to watch the races on Sunday last year. This creates a fantastic atmosphere and I am sure we can expect a similar level of participation this year. This weekend will be another busy one for our technical team as we will be supporting teams in the post-race test on Monday where we will supply some experimental tyres as part of our ongoing tyre development programme.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
“Brno is a rider favourite as it has a fast layout with a wide track and since being resurfaced in 2008 has good, consistent grip levels. This resurfacing has also resulted in the tarmac becoming very abrasive, so the circuit is now more demanding on tyres and requires harder tyre compounds, especially for the front which has to deal with considerable weight transfer under braking into the downhill corners. Many corners at Brno are high-speed and flowing and so the lateral loads generated are substantial, with the right shoulders of the rear tyres put under slightly more stress than the left.
“The medium speed corners require good shoulder stability and traction from the rear tyres on corner exit and it is also really important to find a good setup here, as excess sliding around this fast circuit can result in high levels of tyre wear due to the abrasive nature of the tarmac. Our front tyre allocation for Brno changes slightly this year with the medium and extra-hard options providing the necessary stability and durability needed for this circuit, while the soft option is offered in case of unexpectedly cool conditions. Rear tyre options remain the same as last year with the medium and hard asymmetric options being supplied.”Dunlop Straight Back to Brno
Dunlop’s Moto2 tyres and personnel have a rapid change of timezone and scenery following last weekend’s Indianapolis GP, heading straight to the Czech Republic for the bwin Grand Prix Ceské Republiky at the Brno Automotodrom on August 24-26.
Brno is a fast, clockwise, circuit featuring eight right-hand turns and six left handers over 5.403km of constant elevation changes. It is the right handers that demand most from the tyres and the wide 15m track width also favours high cornering speeds.
Brno has hosted motor racing since the 1930s, with the present track – which replaced the original road layout – making its motorcycle grand prix debut in 1987.
Get a Grip
For Brno the Group D Grip Focused allocation of the 4886 and 3838 rear tyre compounds is allocated. These are allocated to tracks requiring high stability with mechanical grip. The 4886 compound was introduced in late 2011 season with good results. It has the ability to give the rider good initial grip and good life in cool conditions, holding temperature well to compensate for long straight tyre cooling. Has good mechanical grip in slow corners.
The 3838 is the harder option core compound which gives riders the confidence to open the throttle early out of the apex as well as having good resistance to abrasion and wear. Both rear tyres are in the ATR05 construction and are joined by the season-familiar front allocation of the 717 and 302 compounds.
Dunlop Motorsport Senior Service Engineer, Alan Nicholls:
“Brno is a great race track but one of the hardest for tyres, so it’s a place where we have our work cut out.
“The layout is aggressive and includes a lot of elevation – I’ve walked the circuit many times so can confirm this from personal experience! It heads gradually downhill until turn ten, when it changes to heading uphill back to the start/finish.
“On paper, Brno has eight right-hand turns and six left-handers, but only three of those left hands are of any particular note from a tyre perspective,
“The challenges include the weather, which is usually warm, but it is not unusual to see thunderstorms in the afternoon.”
“Brno has one of the longer laps of the season at over two minutes which is something I enjoy. There’s certainly a lot for the riders to think about over the lap!
“The whole circuit is set among a wooded area with a vast natural amphitheatre similar to Donington Park, so it’s a real fan favourite.”
Moto2 Rider Quote: Roberto Rolfo, Technomag CIP, Suter:
“Brno is a very nice track where I always enjoy my riding style. It has many chicanes and up and down hill that make the track special. You need to be fast in corners, keeping a lot of corner speed and have a good engine because of the last uphill part where needs power. It is a difficult track for tyres because both sides are working hard and to be constant during the race need to have a good bike setting to maintain durability on tyres. Both, front and rear needs stability because of hard braking and strong accelerations. Dunlop are always very good tyres for confidence and more the front is the point where I can push more because tyre has a good profile.”
Moto2 Rider Quote: Dominique Aegerter, Technomag CIP, Suter:
“The Brno circuit is quite difficult, the track is wide so you can use many different lines. It also has a lot of up and down, especially the last section uphill with chicane is really tricky. I had a great race there last year, it is not my favourite, but I can score good points there. The track is wide, with many fast and long corners. The grip level is quite good. We often have high track temperatures, so in combination with fast corners, long time on banking, we have to keep an eye in not over-heating the rear tyre. We also need a great confidence in the front tyre to be able to carry high corner speed. I have a very good feeling with the Dunlop tyres, especially with the new front tyre profile.”
