Yamaha's factory rider duo, namely Ben Spies and Jorge Lorenzo, they completed the second day, Wednesday of the tests in Sepang at the top of the charts - but in the absence of the Hondas.

Lorenzo tested an engine with different specifications, as well as Ben Spies who also rode various variations of the electronic package that controls everything on his bike.

Jorge Lorenzo then stated: "We started with a different engine to the one in the previous Sepang test a month ago. But today the comparison of the two engines was difficult, because the track conditions were much worse then and our times slower. The rain did not allow us to complete the day's program, so we have to try harder tomorrow. However, the response of the engine was better today and the entry into the corner was easier".

“I really liked the new engine, it is easier to drive, especially when turning. I feel like I have more traction in the back, which gives me confidence and I can drive the rear wheel even further in a controlled manner. The tears are also smaller now”, completed.

On the other, Ben Spies noted: "Everything went well in the morning. We waited for the weather to improve in the afternoon because the Yamaha engineers had made sure to load us with lots of new parts, so we didn't have time to deal with what everyone else was doing. We have to focus on our work, so that we can methodically check all refurbished parts and evaluate them. We only hope for better weather".

In the first two days all the drivers had a problem with the grip on the Sepang circuit. This is primarily due to the fact that the track surface was very dirty, from the car races that had been held there just a week earlier. But it is also due to Bridgestone's new single tires with a less rigid frame, but which contribute to the creation of chatter, i.e. high-frequency bounces of the rear wheels, especially when braking to enter a turn.

In general, the weather in Sepang at this time of year is good. The temperatures are not too hot but enough to dry the track after the regular afternoon rain. This year, Nevertheless, the midday rain turned out to be a long-lasting storm and prevented the teams from completing their program on the first and second day. Thursday is the last day of official testing.
