The short answer is obsession. The Isle of Man TT is the Mount Everest of motorcycle roadracing. You race in the TT because there is no other challenge in motorsport like it. It’s 37.73 miles per lap of narrow, winding, bumpy, jump-ridden, exotically named and potentially lethal road—not the place for short-circuit types who like to bang fairings and handlebars. Back in 1987, we launched from the start-finish line in pairs, because it was safer that way. These days, it is one bike at a time. So, it’s just you, your motorcycle and the road, the purest roadracing there is. It’s a test of will, concentration, memory and, some believe, guts, and not just because of the danger; you have to be self-confident enough to commit hard to ultrafast sections that were never intended for racing while putting yourself on view of tens of thousands of spectators and a worldwide TV audience. The totality of the TT experience is unlike anything else anywhere in the world, and always has been.
