Formula USA Director of Road Racing Bill Syfan has invited 800cc Ducati refugees from the AMA Pro Thunder class to participate in F-USA Sport Bike races. Under F-USA rules, machines in the Sport Bike class can displace up to 800cc with a minimum weight of 365 pounds and a maximum horsepower output of 112 horsepower on a Dyno Jet Dyno. To be eligible, Ducati 748s must run stock wheels, frames and cases and must compete on DOT-labelled tires. Each F-USA Sport Bike race features a $10,000 purse which pays $2000 to win with $1500 for second and $1200 for third, paying down to 15th.
