Teen motorcyclist Peter Lenz died in a crash at the Indianapolis Motor Speedway. 'Good Morning America' follows the tragic story in which Peter was struck by another rider. "At only 13 years old, Peter Lenz was a rising star on the motorcycle racing circuit, with nine national championships under his belt," reports GMA. Peter reportedly fell off his bike during a practice lap, landing in the middle of the track where he was hit by a 12-year-old rider.

The tragic accident is raising the question: "How young is too young?" According to USGPRU chief steward, Stewart Aitken-Cade, "These kids have prove time and time again that their skills, their training, their background and everything have proven that these guys are more than ready for a track like this." On Peter's Facebook page, his father posted this message, "God bless Peter and the other rider involved... Miss you, kiddo."
