Bridgestone Holds Last MotoGP Tests Until February

The final MotoGP tests of 2008 took place at the end of last week. Eight teams took part in a two-day test at Circuito de Jerez in Southern Spain, while two tested at Australia’s Philip Island Circuit over three days. Reigning world champion Valentino Rossi ended the Jerez test the fastest rider, setting a time of 1.39.429 on the second day, edging out Dani Pedrosa’s first day fastest time of 1.39.525.

The test took place over 26-27 November and fourteen riders took to the track over the course of the two days. On the final day, Pedrosa was second fastest to Rossi, whilst the third to sixth fastest riders, Jorge Lorenzo, Toni Elias, Alex De Angelis and Nicky Hayden, were separated by just 0.06s, illustrating the very close level of competition, even for those riders who have changed teams from the 2008 season.

Bridgestone took the softest compounds proposed for the 2009 season, with two compounds available for each rider. It was the second opportunity for riders to evaluate the 2009 specification tyres, following the post race test in Valencia at the end of October. In particular, Bridgestone was assessing the tyre working range, with Spain providing weather at the cooler end of the spectrum and Australia conditions at the hotter end.

MotoGP now enters the test ban period with the next official test scheduled for Sepang, Malaysia on 5-7 February.

In the Q+A session, held after the weekend’s tests, Tohru Ubukata, Bridgestone Motorsport manager motorcycle race tyre development talked about the purpose of the tests for the supplier: “From our perspective we wanted to assess the suitability of these tyres for next year’s races and in particular evaluate the tyre working range. For this we tested in the relatively cool conditions of Jerez, where the ambient temperature was around 12°C and the track temperature around 18°C. In the cold, the main consideration is grip levels and warm-up time. Philip Island allowed us to look at the higher range of temperatures, as the ambient temperature was around 25°C and the track temperature about 40°C. Here the main consideration is heat durability. In both locations the tyres worked well, so we are confident when we look ahead to 2009.”

He went on to talk about the invaluable feedback the company received from so many of the competition’s drivers: “This has been very good and over the course of next year we will have an enormous amount of rider feedback from all of the bikes on the grid. This is very useful for us as a company when we look to future tyre developments. The surprising thing from these two tests has been how positive all the riders have been about our tyres, and how quickly teams and riders have been able to adapt their bikes and riding styles to suit the Bridgestone tyres, even if they were not using them previously.”

Asked if there would be much development to the tyres during the test ban period, Ubakata responded, “Compared to a competitive tyre situation, we will not be focusing on tyre development. However, there are still minor adjustments to be made, based on the data we have accumulated at these tests and also the Valencia test. Although we will not be developing the tyres as we would previously, we will be working hard. Our new challenge is ensuring that we produce sufficient tyres for all competitors next season and we also have to put all the logistics in place to ensure we provide good and fair service to all teams. This will keep us very busy.”
