Having concentrated on trying new parts for Yamaha yesterday, it was Michelin’s turn today and the Yamaha Factory Racing riders spent most of the day testing new tyres, with the Malaysian temperatures - 28ºC ambient temperature, 40º C track temperature and 56% humidity - providing the ideal proving ground for the latest generation of Michelin rubber, 28º C.

The Yamaha pair consolidated yesterday’s good work with another day of fast times, both dipping under the 990cc lap record pace on race tyres set by Loris Capirossi in 2006 with a time of 2'02"127. Rossi completed a total of 53 laps with a fastest lap time of 2'02"099: “Today we tested some new tyres for Michelin, both front and rear. We haven’t found any special improvements to the front since the last test, but for the rear we tried something interesting to improve the edge grip. I’m very happy because I think we’re working in the right direction and we have definitely made improvements in this area. We have also continued to work on the stability in braking, changing the set-up in order to improve this even more. Finally today we worked on the engine mapping, as this year fuel consumption is going to be a very important factor."

Tomorrow we will make a long run in order to compare with our data from the last test, and it will be interesting to see how all the improvements we’ve made this week make a difference to the performance of the bike over a race-distance.”

His team-mate Colin Edwards completed 44 laps, ending this second session in second position with a fastest lap time of 2'02"118: “It was pretty warm today and I had to go out in the hottest part of the day to test tyres, so that was quite hard work! Anyway we got through a whole lot more stuff today and things are getting better and better. We tested a couple more new things for Yamaha and then did a lot of tyre work with Michelin. Looking back at the last test, just a couple of weeks ago, everything has evolved so much since then it’s amazing! We’ve moved forward an incredible amount over just five days of testing so far this year, so that bodes well. Last time here I was doing low 2’03s comfortably, but this time I’m doing low 2’02s lap after lap and they’re coming so easily, without me really having to push too hard at all. We’ve got a long run to do tomorrow and a few more loose ends to tie up, but we’re in good shape!”

"Today both riders focused on tyres and we had some new material from Michelin," explains Davide Brivio, Team Director. "It was a very interesting day all round. Generally speaking, in these two days we have made small but important improvements compared to the previous test here. Tomorrow both riders will make a long-run and we will see if these improvements will be crucial towards race-performance.”
