Bridgestone MotoGP™ Race Preview - Round 2: Jerez, Spain
Bridgestone slick compounds available: Front: Soft, Medium, Hard; Rear: Soft, Medium.
Bridgestone wet tyre compound available: Hard.
After a thrilling season opener at Qatar, MotoGP™ heads to the Jerez circuit in southern Spain where huge crowds are expected as Europe gets its first taste of MotoGP™ action in 2012.
Jerez is a popular circuit among fans and riders and its balance of left and right-handed, as well as slow and fast turns, makes it technically demanding for riders. From a tyre standpoint, the layout of the circuit puts equal demands on both the left and right shoulders of the tyre and so there is no need for an asymmetric rear tyre. Track temperatures at Jerez for this time of year are usually around the 40°C mark, though rain at last year’s race and in pre-season testing earlier this year are proof that wet conditions are a possibility for the race.
Bridgestone will introduce its new front specification tyre with a revised construction at Jerez, with two pieces being made available to each rider for the race weekend. The new specification tyre will only be made available in the harder compound as the greater durability this option provides makes it better suited for race use.
Recent history shows that the Jerez circuit suits local riders, with Yamaha Factory Racing’s Jorge Lorenzo winning the past two races at the venue, while Repsol Honda’s Dani Pedrosa won in 2007. A first ever win at Jerez will be on the agenda for Casey Stoner on the other Repsol Honda, while Valentino Rossi’s affinity with the Jerez circuit where he has won five times previously will provide extra impetus for the Ducati team as they fight for the podium.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“After the excitement we had in Qatar I anticipate more close racing at Jerez as this circuit has produced several good contests over the years and many riders are in good form at the moment. Jerez is a very important occasion for Bridgestone as not only is it the first time our new specification front tyre is available to riders at a race weekend, it also sees the new wet tyre allocation regulation come into effect.
“After analysing wet tyre performance at last year’s race and pre-season testing in Jerez and ongoing discussion with the Safety Commission, we have decided to change the allocated wet compound for the Jerez race from soft to hard. However, with the new regulation in place if after the first wet practice there is a consensus among riders that the conditions warrant a different wet tyre compound, Bridgestone, following consultation with the Race Director can make an alternative wet tyre compound available. This change in wet tyre allocation is yet another example of how Bridgestone is working closely with Dorna and the FIM to improve rider safety.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Division
“Jerez is a technical circuit with a mix of fast and slow corners as well as some elevation changes and the diversity of the corner layout means a tyre with a balanced character is required to provide good handling in both the low and high speed sections. Jerez has an almost even distribution of right and left-hand corners so we will supply symmetrical rear tyres in the soft and medium compound options.
“Though the track temperature during the race weekend at Jerez is historically high, conditions can be quite variable as evidenced at last year’s race and during pre-season testing this year when rain fell. In addition to the regular front tyre compound choices of medium and hard for Jerez, we are also making a soft front option available this year in case there are unusually cool conditions. The race at Jerez will also be the race debut for our new specification front tyre and each rider will be provided with two pieces of the new front tyre in the harder compound option.”
Dunlop reveals new slimline front in Jerez.
Moto2 World Championship lap times could be set to get yet faster as Official Tyre Supplier Dunlop will unleash a new slimline front tyre for the second round of the championship, the Gran Premio bwin de España – Spanish Grand Prix – in Jerez, Spain on April 27-29.
The new profile – made to Dunlop’s latest construction – will be used for the rest of the season following successful pre-season testing and feedback from riders. It’s a slightly smaller tyre; meaning faster handling and a more precise feel for the riders’ pleasure.
This is the latest step in Dunlop’s quest for continual improvement for the tyres which have provided two seasons and counting of endless excitement since the inauguration of the Moto2 World Championship.
Dunlop’s racing tyres, including this svelte new front, are designed to inspire confidence in the riders who use them, and the technology developed is taken from the track to the road for Dunlop’s road range of motorcycle tyres.
The Spanish Imposition
The Spanish circuit of Jerez imposes a conundrum for the tyre engineer. Its characteristics and location make it an ideal and frequently utilised test destination, made all the better when in can accommodate a wide range of different tyre compounds which can be utilised at the track. This poses the problem; if Jerez is the jack of all tyres, which tyres should be allocated to master it?
Following rider feedback at the recent pre-season test in Jerez, Dunlop has will bring the tyres from the Group B ‘Abrasion Defenders’ range, the 3854 soft and 4886 medium rear compounds. The 3854 is more suited to higher temperatures and the 4886 more suited to cooler temperatures. These rear tyres are allied to the familiar to all rounds of the season 717 and 302 fronts, resplendent in their new profile.
Dunlop’s Moto2 coordinator, Clinton Howe:
“Jerez as is a track which really helps us with tyre understanding and confirming if we are heading in the right direction with our developments. One of the great things about Jerez is that you can use a multitude of tyres here, which is why it’s such a fantastic test venue. This does make things a little difficult in the respect of ascertaining which tyres to bring – as a variety of compounds can work, and work very well, at the circuit.
“Last year we developed the 3854 soft compound which was used successfully in Jerez and this is joined by the 4886 medium at Jerez in 2012. We originally intended to bring the 3854 and 3757 rear allocation, but the riders were so positive about the 4886 medium compound that we couldn’t do anything other than bring it to Jerez to partner the 3854.
“Over the course of the race weekend we generally experience a relatively wide range of track temperatures at Jerez. In the morning the track surface can be quite cool and this means the tyres suffer more from abrasion. In the afternoon the track can be ten degrees Celsius warmer, and the way the tyre works means that abrasion is not such an issue. From a tyre perspective this is quite easy to understand, but for riders finding set-up and being confident on the bike it is a good challenge to tackle.”
Moto2: Julián Simón, Blusens Avintia Racing, FTR:
“Jerez is a very fast track but there are also many challenging corners, and you have to make good use of the brakes. It’s important to get a good set-up with the bike as it’s a long race on an aggressive track for the tyres. Turns eleven and twelve in particular are very fast, then you arrive at the final turn where you have to ensure a good exit on to the uphill straight that follows. You have to focus on how you brake on this circuit and for this you need good confidence in the front tyre. You need an aggressive riding style on this circuit, but it’s a very enjoyable one for riders. Dunlop gives me tyres which I like very much to ride; they give me very good confidence. Dunlop made a big development step from the first season of Moto2 to the second, and now the tyres are much better again. This year we have a new front tyre, and it’s very good I can tell you. For sure, I know Dunlop will make even better tyres in the future, but for now I am very happy with the current ones!”
