Former world champion Nicky Hayden commented after the Sepang testing that Michelin still needs to improve before the season opener at Qatar in early March.

"I can't say we have made a huge step in the tyre department"

"I can see the effort they have put in which is good, but i'd be lying if i said i'd seen a huge improvements on the spec tyres i was using to set the bike up"

"Some guys have found stuff they like, but i haven't come across any tyres that i absolutely fell in love with"
