All six riders will campaign Yamaha’s proven, race-winning R1 WorldSBK machine, which has undergone considerable development over the very short winter break. Engineers at Yamaha Motor Research and Development Europe have focused their efforts on improving specific areas without compromising the strengths of the R1, with improved corner exit acceleration a major goal. This direction was confirmed during a two-day test in Jerez last week, with both the two Pata Yamaha Prometeon WorldSBK riders and the two GYTR GRT Yamaha WorldSBK newcomers finishing promisingly within the top 10. Both days were topped by Razgatlıoğlu, who was tantalisingly close to breaking the WorldSBK lap record on day two.
