Kat Diamond Kiyonaga’s journey into the world of motorcycles didn’t start with speed—it started with curiosity and a deep love for American culture, particularly the 1950s. When she met her husband, Mitsuhiro “Kiyo” Kiyonaga, her admiration for motorcycles turned into something much bigger. With his encouragement, she went from cautiously riding through canyon roads to setting an SCTA land-speed record of 97.192 mph.
Kat’s determination and passion for vintage motorcycles have made her a standout in the community. She embodies the spirit of pushing boundaries, taking on challenges, and proving that with enough grit, anything is possible.
