Parilla was founded in Milan, Italy, in 1946 by Giovanni Parrilla. The company began with a 248cc overhead-cam single that Parrilla raced himself, later developing a DOHC version of the same engine. From there Parilla expanded into road-going motorcycles offered in 98cc, 125cc, and 250cc displacements, building a reputation for well-engineered small-capacity machines among Italian riders of the era.

Under designer Soncini, Parilla broadened its range through the 1950s with models such as the 175 Turismo Speciale and the Veltro twin. The company closed its doors in 1967, and today it remains a relatively obscure but historically notable name in the story of Italian motorcycling. The Parilla name later reappeared on kart-racing engines produced under the IAME brand.

The manuals available for Parilla engines cover engine rebuild procedures, transmission service, electrical systems and wiring diagrams, torque specifications, diagnostics, and scheduled maintenance for these vintage single and twin-cylinder engines. Given the age and rarity of these machines, accurate factory procedures are especially valuable for correct, careful servicing of these rare and aging motorcycles today.

These guides are intended for restorers preserving original Parilla motorcycles, DIY owners maintaining a classic machine, and specialist workshops that work on vintage Italian motorcycles, offering the detailed reference material needed to keep these historic small-displacement engines running smoothly and in proper working order for years to come.
