Michelle Duff

Michelle Ann Duff (born Michael Alan Duff on 13 December 1939) is a former Grand Prix motorcycle road racer.

Riding
Duff's best season was in 1965, winning the 250cc Finnish Grand Prix and finishing the year in second place to Phil Read.

Duff suffered a near-fatal crash in Japan and required extensive surgery and physical therapy. The recovery was documented in the 1967 National Film Board of Canada short documentary film Ride for Your Life, directed by Robin Spry.

Private life
Duff married a Finnish woman in 1963 and had a son with her the same year, and a daughter two years later. In 1984, she changed her name to Michelle and commenced transition, separating from her wife. Following sex reassignment surgery, she wrote about her experiences as a professional motorcycle racer (note that this book is not about her life as a trans woman) in Make Haste, Slowly: The Mike Duff story.
