What did we learn from the first proper MotoGP test of the new era of Michelin tires and spec-electronics? More than we hoped, yet less than we think. A quick run down on the state of play after Sepang, with more to come over the following days.
The riders approached the Sepang test with some trepidation, fearing that Michelin had not fixed its wayward front that caused so many crashes at Valencia and Jerez.
Their fears were unfounded, the new front tires which Michelin brought – a total of five different types, of varying construction and compound – were all a massive step forward.
They were not as stable as the Bridgestones they replaced, but they had gained a lot of predictability and feedback. There were very few crashes that the riders said they had not seen coming.
That does not mean that all of the problems have been solved. A couple of people went down at Turn 5 on Tuesday, in crashes they described as strange. Casey Stoner (more on him later) had a typically concise and thoughtful analysis.
“There’s a little point after probably 45°, that [the tire profile] goes down just a little bit more, that it doesn’t seem to match with the rear with some of the profiles that we’ve tested,” Stoner explained.
“That gives everybody a little bit a nervous feeling, and essentially why people are struggling into Turn 5, a big fast open corner, going in, when the bike goes light, it doesn’t like that feeling. It makes the bike a little nervous, and I think that’s when the front wants to break away.”
