The British Superbike Championship motorcycling series has renewed an agreement with Rock Oil and struck a new deal with WNT.
Rock Oil, a manufacturer of oil and lubricants, has sealed a three-year extension, to run from 2017 to 2019.
Rock Oil will have a range of branding, experiential, hospitality and marketing rights, as well as presenting sponsorship status for the local round at Oulton Park, UK, in September.
WNT, which supplies cutting tools to the metal cutting industry, has agreed a sponsor and engineering partnership with the championship for the 2017 campaign.
WNT will benefit from a range of marketing and communications inventory.
The deals were brokered by MotorSport Vision Racing, the series' commercial rights-holder.
