World Superbike champion James Toseland admits his nerves were tested by his two-point championship winning margin.
Toseland won the title for Ducati in 2004 and Honda in 2007
The Ten Kate Honda rider from Sheffield beat Noriyuki Haga by just two points to claim his second Superbikes crown.
"Having left Brands Hatch in August with a 66-point lead, I thought I had one hand on the trophy so to win by two was nerve-wracking," he told the BBC.
"To win the title once was a lifetime ambition but to win it again, on a different bike, was really humbling."
Toseland, who won the 2004 crown on a Ducati and the 2007 title on a Honda, will compete in MotoGP next year for Tech 3 Yamaha, and said it was very important to him to leave the Superbike arena on a high.
"I did the deal (to move to MotoGP) when I came back from the Suzuka Eight hour race at the end of July, before Brands. It was a fantastic opportunity to take for next year," he said.
"But I always said it was my it was number one priority to win title for Ten Kate.
"I'm very proud - my team were all in tears, and my friends and family were all there on the podium. It was a great day."
