"We are proud to have hosted the championship for 22 years and our continuing passion and enthusiasm for the sport will ensure that our commitment and dedication for staging this year's event will remain just as high.
“However, I'd also like to reassure the fans that we will still be staging world motorcycle racing at the highest level with our continued support of the Superbike World Championship. The ongoing growth of this burgeoning series with an ever increasing number of manufacturers and British riders will help to ensure that it provides close and exciting racing that should attract support and interest to equal that of MotoGP in Britain.
“We are also continuing our support of the British Superbike Championship and two-wheel club racing to prove our dedication and commitment at all levels of the sport."
