The change of official tire suppliers for MotoGP, with Bridgestone departing and Michelin arriving, is arguably the most significant change to the class since the series went to a single tire in 2009.
Changing tire manufacturers has a massive impact on everything, from bike design to rider preference, and Michelin face a huge challenge to get everything ready in time.
Bridgestone helped by staying on for an extra year to allow Michelin to properly prepare, and the tires which the French manufacturer have been developing are looking very promising.
Their preparations have not been helped by conditions. Test days have been hit by rain, with testing severely hampered.
This was also the case at Brno, when the majority of the MotoGP field was due to get their first outing on the Michelins since Sepang, though the factory riders had a chance to test after Mugello.
The rain did give a group of journalists a chance to grill Piero Taramasso, Michelin’s manager of two wheel motorsports activities.
