Rossi and Graham Goodwin have been back in the top 10 of the WRC rankings after finishing in third place at the 2017 season opener.
The pair were among eight riders to take home the championship trophy last year, while Graham Goodwin also won the title at the same event at Brands Hatch last year.
Both riders were given the WIRB-approved helmet of the year award, which is presented annually to the best helmet of its kind.
Rossi and Goodwin have raced in the WMR world championship since 2014, and both finished in the points after winning the Australian Open.
The duo are set to compete at the 2019 season opener in Tasmania.
