From what I've been told, the 2015 R engine has some RS components that were not in the SL engine. I'll try and find the print.
Please do . I don't actually believe there is a actual "RS" . The cams and valves being used in the EVO bikes in WSBK are different but the valves are oversized compared to the ones in the standard R bikes .,
