The sign may indicate a 40mph speed limit, but John McGuinness is already well past 100mph on his Honda TT Legends Superbike in this photo from the 2012 Isle of Man TT.
The shot, by Stephen Davison, was taken just after the Ballacrye section as McGuinness headed to victory in the 2012 TT Superbike race, his 18th TT win.
