The day after an intense race at the Motorland Aragon circuit, MotoGP held its first full Michelin tire test since Sepang this year. The track was open to any teams wishing to give the Michelin tires a spin, or work on the setting of their bikes.

Fourteen riders elected to make use of the opportunity, including both Repsol Honda riders, the Tech 3 Yamaha duo, both LCR Honda riders, and the Aprilia men, along with Scott Redding, Aleix Espargaro, Danilo Petrucci and Valentino Rossi.

Michelin had brought three rear tires and four front tires to Aragon, keen to get some data from the circuit, as they have not had much testing at the track, and very little in the dry.

The post-race Michelin tests have been something of a frustration for journalists following MotoGP. With riders barred from speaking publicly about the tires, and no official timing for the tests, it has been hard to make sense of the events.

Today’s Brno test was even more frustrating. Rain all day, alternating between heavy downpours and a very light drizzle meant that the track was more or less wet all day. The riders stayed in their garages and race trucks, for the most part, with a handful of riders putting in a handful of laps.

Though the test was mostly a washout for Michelin, the French tire manufacturer did get some useful data from the test. Riders went out on three types of tire: slicks, wets, and intermediates, in varying conditions.

On the day after the Italian Grand Prix, the MotoGP riders were back testing at Mugello. This time, however, it was only the factory riders who remained, to give the Michelin tires another run out.

The last time they took to the track on the Michelins was at Sepang, and Michelin had brought the latest iteration of their tires to test.

Due to the commercial sensitivities involved, there was no official timing, and the riders were not allowed to speak to the media about the test.

Unsurprisingly: Bridgestone holds the single-tire contract for the 2015 season, having spent a lot of money for the privilege, so they do not want Michelin stealing their PR thunder.

Nor do Michelin really want to be subject the intense scrutiny which official timing would impose while they are still in the middle of their development program.

That does not mean that the small band of journalists who stayed at the test did not learn anything, however.

The competitors for the 91st Pikes Peak International Hill Climb have just concluded a two-day tire test at the Colorado road course, and it should perhaps come as no surprise that our boy Carlin Dunne has posted the outright fastest lap for a motorcycle during the tire test (the Santa Barbara native set the outright two-wheeled course record last year on his Ducati Multistrada 1200 S).

What is surprising about Carlin’s result at the tire test is that he was on the Lightning Motorcycles electric superbike. That’s right, the fastest bike so far for 2013’s Race to the Clouds is a 200+ hp electric superbike that is refueled with solar energy. Petrol heads, eat your heart out.
