A Brief History of the Italian Marque
Motocross rider Andrea Mosconi built his own Eurocross motorcycles using Aermacchi Harley-Davidson two-stroke engines.
In 1973 he founded the Hiro s.a.s. based in Origgio (Varese) which built engines used by other motorcycle marques.
Two-stroke engines of 175, 250 and 350 cc were constructed, and in the nineteen eighties produced 125 and 250 cc powerplants for motocross, enduro and road use, and a 320cc trials engine which powered the six-speed Sammy Miller developed by Tau.
Manufacturers who employed Hiro engines include:
Hiro also built a sport aviation engine of 23hp
Production ceased in 1986.
