John A. Wittner


A legendary innovator for Moto Guzzi and driving force in the motorcycle community, Dr. John A. Wittner, DMD, age 78, of West Chester, PA, passed away on February 15, 2024. He was the son of Howard Wittner and Victoria (Shenker) Wittner, and brother to Ken Wittner, who pre-deceased him. “Dr. John,” as known to friends, colleagues, patients, and members of the motorcycle community, was intensely dedicated to his craft, whether it was complex dentistry without pain — or mechanical innovation and next-level mastery in motorcycle engineering.

Studying mechanical engineering at Lehigh University (always with a love of fixing things), he applied his inherent talent and skills to help improve human performance, and graduated from University of Pennsylvania Dental School, as DMD, and was partner to Dr. Bill Deal, in Deal-Wittner Dental Health Group for many years. But for decades, he kept on building engines for motorcycle racing, channeling the magic into Moto Guzzis that won and won and won.

One day, he reached a turning point while working on a friend and patient in the dental chair – who encouraged him to take motorcycle racing from the local to the big time. And that’s how the legendary Dr. John’s Team Moto Guzzi was launched and went from an experienced, dominant group of regional racers to winning and dominating the 1984 AMA National Endurance Racing Championship at the Daytona Firecracker 400. And went on to design and engineer unique marques for Moto Guzzi in Italy, leaving an historic legacy for motorcycle racing.

Dr. John was a Vietnam veteran, loyal friend, and independent individual who always rose to a challenge and who’d rather be burning rubber than anything else.
