Jorge Lorenzo, the 2010 and 2012 MotoGP World Champion, slipped to sixth on the Sepang test Day Two timesheet, but he did improve by half a second on his Tuesday best and got through some important work on electronics settings.

Lorenzo’s best time of 2:00.573 — on the 27th of his 49 laps — on Wednesday left him 0.647s behind title rival and pace man Marc Marquez, but also behind teammate Valentino Rossi and the likes of FTR Yamaha-equipped compatriot Aleix Espargaro.

Lorenzo and Rossi worked through a number of different test items for the Yamaha engineers as well as some tire testing for Bridgestone. The Spaniard made some improvements to the electronic setting of his YZR-M1 to provide further corner stability, leaving him happier with his feeling than he had been on Day One.

“Apart from the position, which is not ideal, I think we made a step forward,” Lorenzo said. “Changing something in the electronics, we improved the behavior of the bike in the corners, and it is now more like last year.

“I can keep a more constant pace and be a little faster for one lap. We need to keep working, as our rivals are strong at the moment, but today I’m more happy than yesterday.”

The three-day test at Sepang will conclude on Thursday afternoon.
