In 2010 he failed to take a podium at the North West 200, with his best result being fourth in the second Superbike race.
He went to the Isle of Man TT, looking to achieve his first TT victory.
However, the meeting was dominated by Ian Hutchinson, who took a record-breaking five victories in all the solo races, and Martin suffered serious injuries in a major crash in the final race.

Prior to that crash, during the Superbike race, Martin received a 30-second penalty for exceeding the posted pit lane speed limit of 60 km/h by just 0.112 km/h.
Had he not received the penalty, his overall time would have been 1:46:48.05 and put him in 2nd place, behind Ian Hutchinson who finished with a time of 1:46:31.82.

His performance at the TT was criticised by Simon Buckmaster, whose Performance Technical Racing built the bikes which Martin was running.
He accused Martin of not listening to his race advice, arguing "He needs to stop being distracted and lift his professionalism.
Instead of being a TV star and courting publicity 24x7, he should be concentrating on racing and what's needed to win.
Get his focus and concentration into racing, not promoting his name and money-spinning deals."
He also cited disrespectful behavior during the race and bad language and criticism directed toward a member of PTR in a magazine interview.
Martin received considerable public support over both the nature and timing of Buckmaster's comments, coming as Martin was still recovering from the crash, but in a subsequent interview Buckmaster defended what he had said, arguing he was not slating him and stating Martin had no issue with the comments.
