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.
In the short term, Yamaha's seamless gearbox is likely to be the most important development. It has not been officially confirmed that Yamaha will be bringing the full seamless gearbox (seamless in both upshifts and downshifts). Officially, people wearing Yamaha shirts will tell you that nothing has been decided yet, but well-informed gossip says that the seamless gearbox will be there, for both Valentino Rossi and Jorge Lorenzo. Yamaha's test riders have been using it for several months now, Colin Edwards having tested it extensively at the end of last year.
