25. Guy Martin

Injury Sustained: Fractured spine, bruised lungs, twisted ankles
Raced In: British Superbike Championship
Complex Says: Make no mistake--the Isle of Man TT is a serious motorcycle event. In 2010, a major crash involving Guy Martin during the Senior TT resulted in the very first red flag in the race's history. The bike burst into a fireball, the size and intensity of which some Hollywood effects guys should study. Luckily, it looked much worse than it was--Martin was conscious when the medical team arrived. What did he do after he got out of the hospital? Back to the garage, of course. He had another TT to prepare for.
