John McGuinness has set the benchmark in the blue riband Superbike class at the Isle of Man TT for the best part of a decade.
The 40-year-old from Morecambe remains unbeaten in any Superbike race he has finished on the Mountain Course in the last nine years.
He is the second most decorated TT rider in history with 19 wins to his name behind Ulster legend Joey Dunlop, who tops the roll of honour with 26 successes.
McGuinness will return to the TT with the Honda Legends team next year but is expected to face a serious threat from young pretender Michael Dunlop, who has earned himself a factory Honda for the event next June alongside McGuinness and British Superbike veteran Michael Rutter.
Will Dunlop be the man to finally halt the McGuinness juggernaut at the TT, or will the popular English star prove yet again that he is still the master of the greatest road racing circuit in the world?
Perhaps Guy Martin will finally win his first TT race, or maybe Cameron Donald can rise to the occasion and add a second Superbike victory to his record following his memorable success in 2008.
Kiwi Bruce Anstey is another rider capable of challenging McGuinness for Superbike supremacy, while Conor Cummins, Gary Johnson, Rutter and William Dunlop will also expect to up the ante in the feature class.
Let us know who you think will be the man to beat at TT 2013!
