It seems safe to say we are living in a new Golden Age of MotoGP. The stomach-churning tension of 2015 was followed by an unimaginably wild 2016 season, the racing turned on its head by the combination of Michelin's first season back in MotoGP and the switch to fully spec Magneti Marelli electronics. 2017 saw the surprises keep on coming, with new and unexpected names such as Andrea Dovizioso and Johann Zarco becoming serious factors in the premier class. The field got deeper, the bikes more competitive, domination a thing of the past.

All the signs are that this trend is going to continue in 2018. Preseason testing has shown that there is now little to choose between four or maybe five of the six different manufacturers on the grid, while the sixth is not that far off being competitive as well. Where we once regarded having four riders capable of winning a race as a luxury, now there are ten or more potential winners lining up on a Sunday. This is going to be another thrilling season, with the title likely to go down to the wire once again.

Once upon a time, winning a championship meant being on a factory Honda or Yamaha. The balance between the two bikes shifted from year to year, as one of the two would find an incremental improvement the other couldn't match. One year, Honda would find more top speed which the Yamaha couldn't compensate for. The next, Yamaha would add stability on the brakes, which allow its riders to match the Honda going into the corner, then leave it for dead on the way out. It was a game of small steps, the championship swinging one way then the other.

Have we emerged any the wiser after three days of testing at the Chang International Circuit in Buriram, Thailand by the MotoGP field? That is hard to say. The test was more for the benefit of Michelin than for the teams, and the French tire maker brought some 2000 tires for the 24 riders who took part in the test. The track itself was not particularly challenging or instructive in terms of understanding how well bike development was going. "This track is also not so easy or so difficult, it's intermediate," is how Monster Tech 3 Yamaha replacement Hafizh Syahrin summed it up.

Is it possible to draw conclusions about how the 2018 championship might play out on the basis of the Buriram test? "No, impossible," Ducati's Andrea Dovizioso said, before proceeding to do just that in some detail. "I can see Marc in a better shape than at the beginning of last year," Dovizioso said. "I can see Dani in a good shape, I can see Zarco with a little bit more experience, so a little bit better for the championship than last year."

It was harder to judge the Movistar Yamahas, Dovizioso said. "It's very difficult to understand the two factory Yamahas, because they will be fast in the race, on race weekends, for sure. But when you look at the riders and the teams from outside, it's impossible to know the details, so I don't know. I can see the Pramac riders are fast, they are happy with the bike, so I think they will be quite fast during the season."

Normally, when comparing times from a test, it makes the most sense to stick to a single year. But sometimes, there are good reasons to look back at past years, in search of a larger and more universal pattern. Comparing the best laps of riders who were in the championship last year and this year proves to be a highly instructive exercise.

Doing that, there is one thing that immediately leaps out at you. The two riders who improved the most between the two seasons are the two who switched between a Honda and a Ducati. Honda riders will freely tell you that the RC213V is very physical to ride, and the fate of rookies who have come into the championship on a Honda has not been great. Tito Rabat came to MotoGP as Moto2 champion, but struggled to make an impression on the Honda. On a Ducati, he finished the test ahead of factory riders Aleix Espargaro and Andrea Iannone, and just seven tenths behind Lorenzo on the Ducati.
