The AMA (American Motorcycle Association) organized in the 70’s the 200 miles of Daytona in Florida.
This event included two separate competitions, 200 miles for motorcycles up to 750 cc, and 100 miles for 250 cc motorcycles.
However, the regulation allowed the 350cc to run if the engine had only a single cylinder.
Most of the bikes entered in this 100-mile race were Yamaha TZ 250 two-stroke two-stroke In 1973, Kawasaki produced a 350cc single-cylinder, two-stroke, rotary distributor called Big Horn.
Randy Hall, the Team Hansen engineer who was preparing the Kawasaki 750 H2R for the 200 miles of Daytona had the idea of preparing a competition Big Horn to engage him on the 100-mile race of Daytona 1973.
