Dave Lloyd has been involved in motorcycle racing for 60 years. He finished runner-up in his first race, in the Canadian Junior Championship at Harewood Acres, and was soon promoted directly from the Junior to Expert class by the Canadian Motorcycle Association. He progressed through the ranks and made his FIM World Championship debut in 1965.

From 1966 to 1968, Lloyd raced across Europe, against world champions and the stars of the day, in locations ranging from England and Isle of Man to the Netherlands and Czechoslovakia. He had several mid-field finishes in Europe and won both a Bronze TT Replica Trophy and Silver TT Replica Trophy during that time.

Lloyd then returned to Canada and rode in various disciplines in the 1970s. More recently, he made land speed record attempts in 2009 and 2011 and competed in the VRRA Period 1 350cc class Championship in 2021, winning the class title at 81-years-old.
