A Brief History of the Marque
The firm was established by Luigi Pellini and Mario Ferraris, a lawyer, at Via Vigone No. 29, Turino.
Initially they produced bicycle auxiliary engines built under license to Patrick Engineering of Great Britain. Ferraris left in 1924, and Luigi Pellini continued to built the MotoBici Simplex, and developed complete motorcycles with two-stroke engines of 123cc.
In 1927 four-stroke models were produced using the company's own OHV engines of 149cc, 174cc, and 210cc
The 150 was the their most popular model for 1927 and 28. A 175 was presented for the 1929 season, continuing until 1930 when the "new Simplex" models arrived. These were distinctly motorcycles, as opposed to the earlier machines which had the appearance of a motor bicycle. The 1930 175cc OHV Ala d'Oro was followed in 1934 by a 500cc version.
After the war there were similar machines with 148cc and 248cc engines.

Simplex Ala d'Oro WANTED
Hello, I live in USA and I am looking to buy a 1930-36 Simplex Ala d'Oro 175-210cc motorcycle made in Turin, Italy. Please contact me.
Hello, I've sent a scanned image of a restored '37 210cc Simplex Ala d'Oro. This is exactly the model I'm looking for. I hope you can use it.
The bike in the image was from an Italian dealers website ( www.motoold.it ). The bike was sold in 2004, I think. These are pretty rare machines, even in Italy where almost all of them still reside. I think they never made more than 300 a year in the 30's ... if 20-30 still exist, I'd be surprised.
I am looking for this bike because it had an attractive and compact unit-construction engine which was modern for its day. Italian motorcycles in the '30's were in many ways more advanced than British machines.
