Bridgestone wet tyre compounds available: Hard (Main), Soft (Alternative)
Round sixteen of the 2012 MotoGP™ season takes place at Sepang International Circuit, a real test of man and machine with its high ambient temperatures and technical layout.
Comprising ten right-hand and five left-hand corners and measuring 5,548 metres in length, Sepang’s standout feature are its two long straights that demand excellent stability from the front tyre due to the very hard braking zones at the end. The rest of the circuit is a mix of high and low speed corners that overall place a lot of stress on tyres – particularly at the front.
Following in-depth analysis of tyre performance at Sepang over previous years, Bridgestone has altered its selection of rear slicks for this season. The symmetric medium compound slick remains but the harder rear slick this year will be asymmetric in construction with the same medium compound rubber on the left shoulder as the symmetric slick combined with the hard compound rubber on the right shoulder for enhanced durability in hot conditions. Due to its location in the tropics, Sepang is the only race on the calendar where the soft compound front slick isn’t supplied, with the hard and extra-hard front slicks provided to give maximum stability in the severe braking zones at this circuit.
Owing to its high ambient temperatures the main wet tyre for the Malaysian Grand Prix will be the hard compound option and being located in the tropics, sudden wet weather is always a possibility at Sepang.
Hiroshi Yamada - Manager, Bridgestone Motorsport Department
“This will be the third time this year we have visited the Sepang circuit after the winter tests at the beginning of the year and all the hard work put in by the teams and riders will be very important in establishing a setup for this weekend. The level at which Dani and Jorge are riding right now is very high and they continue to push each other to the limits to the delight of all of us who get to see them compete. Sunday’s race will start later in the day than usual at 4pm and there is a strong chance of rain throughout the weekend. I hope that the weather doesn’t have an impact on the race and that we can enjoy a thrilling contest at this fantastic circuit.
“Of course, it will be with a heavy heart that we participate in this year’s Malaysian Grand Prix as we remember Marco Simoncelli. I believe everyone in the paddock will be thinking of Marco throughout the weekend and will do all they can to ensure the MotoGP fans of the world are treated to a show that is worthy of his memory.”
Shinji Aoki - Manager, Bridgestone Motorsport Tyre Development Department
“Sepang is characterised by its two long straights which contribute to it being the second longest circuit on the calendar and the generally high track temperature which is often above 50° Celsius. It is one of the fastest circuits of the season with a mix of high speed corners and tight hairpins and features two extreme braking cut-outs at the end of the two straights. The braking zones demand high levels of stability from the centre section of the front tyres, while the high speed corners demand good shoulder grip and durability.
“A good bike setup is important here to ensure good tyre durability in the high ambient and track temperatures and in this regard, the data acquired during the pre-season tests here will be very important to teams this weekend.”Dunlop tackles Hot and Sticky Customer in Sepang
Dunlop’s Moto2 tyres move to Malaysia for the 15th round of the Moto2 World Championship with the Malaysian Motorcycle Grand Prix which takes place at Sepang International Circuit on October 19-21, the second race in succession where the new 345 compound front tyre is called into service in place of the more familiar 717.
Hot and Sticky
Sepang has a number of challenges as a circuit. Built as a Formula 1 venue, the track layout includes two long high speed straights to test the structural integrity of the tyres’ makeup. The weather is frequently hot and humid, which affects the chemical bonding of the rubber to the track surface. Afternoon tea-time is often heralded by the short, sharp, shock of a momentary monsoon to dampen the track and its inhabitants.
As well as the straights, there is also an intriguing mix of corner types keep the tyres well exercised over the course of its 5.548 clockwise lap, which is completed at one of the highest average speeds of the season.
Sepang will see the rear combo of Group A – Baseline in use, with the two soft compounds of 3757 and 3854 pressed into play. 3757 was initially introduced as the high ambient tyre in late 2010 but has subsequently proved itself more durable in cooler conditions on less aggressive circuit surfaces so gets let out of the factory more often. The 3854 is the softer option core compound offering very consistent performance, being usable at many different circuit types.
This will be the second race where the otherwise season regular front 717 compound is rested and the 345 is called into action. After utilisation in Motegi, where conditions played to its 302 compound partner, Dunlop will continue with evaluation of this tyre in its continued quest for performance improvement for the remainder of this season and beyond.
Dunlop’s Moto2 Operations Manager, Clinton Howe:
“Sepang is the second of three in a row so it’s a pretty intense time of the year! Sepang is a bit of a tricky customer. No matter what you try in terms of tyres, it’s always hard to achieve a similar level of grip as we see at other circuits, particularly because of the circuit layout and the weather conditions. Over the years we have tried numerous approaches, yet it seems impossible to find a tyre which is perfectly matched to the circuit due to the compromises required; but we keep working to find the perfect tyre for these difficult conditions. You can certainly say we learn a lot, and this is a very important aspect of our involvement in Moto2 as our tyre technology is permanently pushed.
“The humidity and the frequent afternoon thunderstorms mean that the circuit surface never fully rubbers in as there is almost a ‘sweat’ on the track surface, it’s consistently greasy. The rain usually comes at around three or four ‘o’ clock in the afternoon, pretty much every day. It’s usually very similar conditions – and this seems to be the case no matter what time of the year we visit!
“Our wet tyres are pretty good – as has been confirmed a number of times this season – but sometimes the rain is so intense that running has to be stopped due to a lack of visibility. Equally, the rain can be amazingly localised, one part of the track can be dry, one part heaving with rain – or even one part of the pit lane wet, another dry. A wet track usually equals a cooler track, but in Malaysia the temperatures of often pretty high.
“The two long straights and the corner setup means that you can consider Sepang almost as two circuits – a left handed one and a right handed one. Over the course of a lap you have in effect all left turns, a couple of long straights, then all right hand turns. This means that one side of the tyre isn’t used for around half a lap, then the other side faces a similar experience. Because it is a balanced circuit in terms of number of left and right turns and demands, you can’t do anything clever with an asymmetric tyre, so all in all, Sepang’s quite a challenge!
“Motei was a particularly satisfying event for us. Conditions were in the sweet spot with track temperatures never low or high, staying in the 30°C – 35°C region all weekend. This meant the tyres worked very well and performance only improved with more set up time.
“The new front 345 was received well but was never really called for as the softer option was more than enough to give good performance. Rear tyres were quite even on the first day of practice but after more time on track the 4886 option became the favourite. Post-race all tyres showed very good appearance and riders were very complementary about tyre performance. The top two finishers were below the 2011 lap record on every lap but two, and both set new lap records on the penultimate and last laps. The Motegi race was over a minute shorter than 2011’s race so we’re sorry that we’re shortening the Moto2 race enjoyment.”
Moto2 Rider Quote: Ratthapark Wilairot Thai Honda PTT Gresini Suter:
“People think that Motegi is a hard braking circuit but I think that Sepang is harder on the brakes. I like the back part of the track but not the front part because it is too much stop start. At this track I need lots of support from the front tyre for braking and lots of traction from the rear, especially when the track gets very hot. I have had good confidence up to now with Dunlop’s tyres and they have been working well.”
