Ernesto Ancillotti founded Ancillotti Meccanica in Florence in 1907. His son Gualtiero followed in his footsteps and opened his own workshop, "G. Ancillotti - Specialità Moto," at 6/8 Rosso, Via Santa Monaca in the historic Florence neighborhood of San Frediano in 1938. In his workshop, he made modifications to the WLA, the famous Harley Davidsons of the time, making the rigid frames of these motorcycles more flexible. It was 1948, and this modification was revolutionary and cutting-edge for that era. By the mid-1960s, G. Ancillotti successfully focused on modifying Lambretta Innocenti scooters, setting World Records at Monza in 1965 and Elvington in 1966, and also worked on road motorcycles. The start of motocross motorcycle production began with the Beta Camoscio 50 cc, nicknamed "number one" in the Ancillotti household. This first motocross bike was transformed by G. Ancillotti with special parts made in a very artisanal manner: a cast iron head and cylinder, the best suspension of the time from Ceriani, both front and rear, and off-road tires. After this initial success with modifications, Gualtiero Ancillotti moved on to producing mechanical parts and engines to enhance performance, including heads, cylinders, and other accessories for off-road motorcycles. There were also modifications made to road motorcycle models, such as the fairing, tank, and tail of the Ancillotti 60 cc Velocità. Following the production of the first cross models, the Florence-made motorcycles became famous not only in Italy but also abroad. The Ancillotti brand was well-known and appreciated in Sweden, the Netherlands, Germany, Switzerland, Spain, France, and Finland (where Kari Tiainen mentioned in an interview that one of his motorcycles was an Ancillotti). These countries brought great satisfaction to the Florence brand, both in sales and sporting achievements. Many riders from the Ancillotti team from 1968 to 1971 included Roberto Rogai, Giovanni Landi, Paolo Cozzi, Adami, Birbes, Paolo Corona, F. Melloni, Missio, Alberto Ancillotti himself, Piani, A. Micozzi, and many others who won in regularity and cross competitions at regional and national levels. From '72 to '75 - '76, with motorcycles equipped with Sachs and later Hiro engines, riders like Pietro Polini in the 50 cc class (Italian Champion 1972) and the legendary Giancarlo Curradi in the 125 cc cross class (Italian Champion '71 - '73) were prominent. Notably, Curradi participated in the 1973 World Championship final at the FIM 125 Prix in Zabok, Yugoslavia; he had to retire due to a broken chain while he was in second place. Giovanni Landi, L. Picco, Franco Picco, Dal Brun (Italian Champion 1976), Lolli, Santi (Italian Champion 1975), Pietro Caccia (third overall and gold medal in the 50 cc class at the Six Days in 1976), the Florentines Marco Barca in 125 trial, Roberto and Luigi Rogai in regularity, Walter Reggioli in 50 cc regularity, Maurizio Morganti Italian trial champion 125 in 1977, Aroni, R. Cancelli, G. P. Findanno, F. Meoni, M. Parrini, Pelanconi, R. Rogai, Tironzelli, Swedish rider Tommy Holson, and many others were also part of the distinguished Ancillotti team.
