Usually, there is a difference in performance between MotoGP prototypes and WSBK race machines. Jonathan Rea and Kawasaki WSBK team were testing at Jerez circuit, alongside MotoGP riders and team. Surprisingly, Rea's Kawasaki was faster than MotoGP competitors.
Important thing to note is that majority of the top MotoGP teams and riders were not present at Jerez. Satellite and other back runners were testing their 2017 race machines. Only fourteen riders participated in the combined MotoGP and WSBK winter test at Jerez circuit.
Jonathan Rea was faster than Alvaro Bautista who rides Ducati's GP 16 MotoGP prototype. Loris Baz was third fastest and was closely followed by Tom Sykes from WSBK at the Jerez test. It is great to see that WSBK machines are catching up with MotoGP prototype machines.
MotoGP teams make use of completely prototype technology, it uses the competition as a base to test technology that will feature on future street motorcycles. WSBK, on the other hand, utilises street machines that are tuned and prepped to get the maximum performance from them.
During 2016 Jerez GP, Valentino Rossi set pole position. Jonathan Rea was 0.015 seconds faster on his Kawasaki ZX-10R WSBK machine with a lap time of 1 minute 38.721 seconds. MotoGP riders during 2016 recorded slower lap times owing to new tyre supplier Michelin.
