About Velocette

Country of Origin: United Kingdom
Founder: Veloce Ltd. (Goodman family)
Best Known For: Refined singles (KTT, Venom) and innovative engineering (positive-stop gearshift)

Company History

Velocette balanced craftsmanship with racing credibility—TT-winning KTTs, roadgoing Venoms, and clever solutions like the positive-stop shifter. The bikes were light, sweet-handling, and mechanically elegant, rewarding riders who valued finesse over brute force. Financial pressures ended production, but the marque endures in clubs where meticulous rebuilds keep the satin-smooth single alive. Historically, Velocette stands for the beauty of one well-tuned cylinder and a frame that sings through your fingers.
