John "Hopper" Hopkins is a former motorcycle road racer based in the United States. During 2017 he raced in the British Superbike Championship aboard a Ducati 1199 Panigale for Moto Rapido Racing, but suffered injuries from a crash at the season-finale race meeting in October, meaning he could not participate during 2018. He has not made a full recovery, which has so far precluded hopes of a comeback, but he has become involved in rider coaching.

Joe Roberts is an American professional motorcycle racer. Roberts competes in the FIM Moto2 World Championship with OnlyFans American Racing aboard a Kalex chassis bike.
