The GP17, however, was a positive change for two riders, both of whom switch manufacturer: Tito Rabat (Reale Avintia Racing) and Jack Miller (Alma Pramac Racing). Rabat made the biggest leap as he gets acclimatized to life on a Ducati, a stunning 2 and a half seconds quicker in the Sepang test this year. And Miller’s impressive performance since switching to Ducati continued, with the Australian making a gain of a full second. Scott Redding, however, moving to Aprilia Racing Team Gresini, lost out slightly – but teammate Aleix Espargaro, now in his second year on Noale factory machinery, gained two tenths.
