 In 1998 Willis was a wildcard ride in the Superbike World Championship at Phillip Island saw Willis finish 6th in Race 1 and 9th in Race 2.This was on a private Suzuki, all the more impressive as he beat both factory Suzuki riders along with many of the other WSB regulars.He competed in both the Australian Superbike and Supersport until injury sidelined him for the final two rounds of both.
