"Going back to the track build, at the moment things are going really well and I would say that there's nothing that needs changing. Justin Barclay has been working very closely with Gareth Hockey on the layout, and they both know what they're doing. I really think this year is going to be even better than last year."

Mackenzie is looking forward to returning to Mallory Park at the end of May for the race, where he can once again count on the enthusiastic support of the British fans.

"The British Grand Prix is always one of the best on the GP calendar, and it's hugely important that everyone gets behind us to make it a great event. I want everyone here with British flags and air horns, cheering the British riders on, because it gives us that extra bit of motivation. In return, we'll be doing our very best to reward them with a good result," concluded Mackenzie.

The Motocross Grand Prix of Great Britain also incorporates the British round of the World Supermoto Championship.
