The engineers have had two weeks to pore over the data from the first MotoGP test at Sepang, identify problems, analyze strengths, and find more ways to go faster. Their analyses have been translated into designs, into new parts, into yet more software, ready to put their theories into practice.
On Monday morning, at 10am Malaysian time, the MotoGP riders get to try out all of the new parts and ideas thought up by their factories and teams in search of a few more fractions of a second.
The eyes of the world will not be on what the engineers did between Sepang 1 and Sepang 2, however. Attention will be focused on Yamaha and Ducati, who will be testing hardware which has been a long time coming.
Yamaha is bringing its fully seamless gearbox to the Sepang 2 test, and Ducati will roll out its Desmosedici GP15 for the first time. Both could make a significant impact.
