MotoGP stars got back to action earlier this week in the first test of the new year at Sepang International Circuit in Malaysia. It was a busy three days for all of the riders as they came to grips with the new era of MotoGP - spec ECUs and Michelin tires. There were some surprises: A normally dominant Repsol Honda squad played catch-up, Danilo Petrucci out performed his factory Ducati counterparts, and a massive front-straight crash caused by a rear tire for Loris Baz. And then there were some things that weren't so surprising... The reigning World Champion Jorge Lorenzo reasserted his dominance, setting a strong pace even when not feeling well. It also marked a big return for two-time World Champion Casey Stoner, who got speed pretty quick for a semi-retired rider.
