Uncini was born at
Recanati,
province of Macerata. He made his debut as professional
motorcycle road racer in the 750cc class with
Laverda, moving later to
Ducati, with whom he earned various titles as Italian champion. His first year in the
Grand Prix World Championship was with
Yamaha in
1976, in both the 250cc and the 350cc classes. The following year he continued to race in both classes, this time with the
Harley-Davidson team, winning two Grands Prix in 250cc (Grand Prix of Nations and Czechoslovakia) and finishing second in championship behind
Mario Lega. However, his quarrelsome relationship with teammate
Walter Villa forced him to move back to Yamaha. He went into a coma, but eventually recovered. He retired from motorcycle competition after the
1985 season. Today, Uncini acts as
Fédération Internationale de Motocyclisme Safety Officer in
MotoGP. ==Career statistics==
