A dozen years ago, as the Isle of Man TT's 100th anniversary crept into sight, there were rumblings the epic race would die, a victim of bad PR and an even worse safety record. But today, as this year's 110th edition showed, the event is a rejuvenated beast, with new riders, new sponsors, new records, fewer deaths, and even more fans—so many the Island can't possibly hold them all. Of course, there's nothing like the TT. Blue-collar heroes like Michael Dunlop (left) do what most MotoGP stars would never attempt, namely racing flat-out on public roads with walls, signposts, and death inches away. If you've been there, you know. If you haven't, these photos will give you a glimpse of why the Island is considered by most to be the final frontier in roadracing.
