In the early 1980s Charles Hewitt, the now Managing Director, but at that time fledgling marketing and salesman, took to the fields and circuits and began to build relationships with professional racing teams. The first major partnership was the support of the 'Team Green' Kawasaki Motocross team of the mid eighties which started Rock down the path of motorcycle racing support. So much so that many people still remember the team and Rock’s involvement over 25 years later. David Thorpe, 3 time World 500cc MX Champion, was a part of this team and still runs on Rock Oil a quarter of a century later in the CCM factory team who contest the World MX1 series.

The intervening years have seen a succession of who's who in racing running under the Rock banner.
