Parilla
In the mid-1940s, on the southeastern edge of Milan, in a district called Ville Sabotino, a man named Giovanni Parrilla ran a small operation fixing diesel injection pumps. He held the Bosch spark plug agency for the area, which was enough to keep the lights on even through the worst years of the war. He was not, by trade, a motorcycle man. But like a lot of Italian mechanics who came out of the war with skilled hands and no shortage of ambition, he looked at the wreckage of the Italian economy and saw a country that was about to need cheap, well-built transportation very badly. Parrilla started drawing up a motorcycle engine. When he put his name on the company, he dropped one of the two R's — Parrilla became Parilla — and the marque that would earn a strange, outsized reputation for a firm of its size was underway.
Origins and the First Machines
The first prototypes were the work of engineer Giuseppe Salmaggi, and by the autumn of 1946 they were ready to run. Rider Nino Grieco debuted the new machine at Lecco, a 248cc single-cylinder four-stroke with an overhead camshaft — sophisticated architecture for a startup with no track record and a workshop background in diesel pumps. A year later Parilla had refined it into the Super Sport, a 247cc SOHC single making 17 horsepower at 7250 rpm through a four-speed gearbox, respectable figures for the era and a clear signal that Giovanni Parrilla intended to build performance machines, not just utility runabouts.
The early lineup diversified quickly. By 1950 Parilla was building 98cc and 124cc two-stroke singles to catch the bottom end of the booming Italian commuter market, and two years later the company added a 348cc overhead-valve single. Around that same period came the first of the small-bore four-strokes that would define the marque: the 175 Fox, a 174cc single that carried the earliest version of what Parilla called Camme Rialzata — the high-cam engine.
The High-Cam Era
The high-cam architecture is the thing serious Parilla people talk about, and for good reason. The chain-driven camshaft sat high on the left side of the engine, well above the crankcase, and used a single lobe to actuate both intake and exhaust valves through unusually short pushrods. It was a clever middle path between a full overhead-cam design and a conventional pushrod engine, giving much of the high-revving character of the former with less complexity and cost than the latter. The design is generally traced to a 1952 Milan Show appearance in the Fox roadster, though sources differ on exactly when full production of the 175cc high-cam engine actually began, with some accounts pointing to the following year — but there's no dispute about what came next: Parilla used this engine, in various states of tune, across more than twenty models over the following decade.
The engineering credit itself is not entirely settled. Some sources point to Salmaggi and Alfredo Bianchi for the Fox's design, while others credit a designer named Soncini, who several sources place at the firm in the early 1950s and who helped broaden the range that followed. Whoever deserves the final word on the drawing board, the effect was the same: Parilla had found an engine format flexible enough to power everything from mild touring bikes to genuine 100-mph sport machines, and the company spent the 1950s wringing every variation it could out of the formula.
The 175 became the workhorse of the range, built in Turismo, Sport, Competizione, and MSDS forms, the last of these — Motocicli Sport Derivati Dalla Serie, roughly "sport motorcycles derived from the production series" — becoming something of a hallmark in its own right. The Gran Sport (GS) versions, tuned hard, were capable of reaching 100 mph, extraordinary for a 175cc pushrod-and-cam single of the period, and easily adapted from road machine to road racer with a change of tires and a few removed parts. Alongside them came the Wildcat, a purpose-built off-road scrambler using the same high-strung engine out of the expensive Grand Sport road bikes, built specifically for the American market, where European manufacturers were discovering there was real money to be made in desert and scrambles racing.
Not every experiment paid off. In 1953 Parilla built the 250cc Setter and 350cc Greyhound, vertical twins aimed squarely at American buyers who, it turned out, weren't particularly interested — the twins never found the following the singles did. The company had more luck staying small and clever: the 1958 Slughi, a lightweight 98cc offered in both two-stroke and four-stroke form, and the 1960 Oscar, a 98cc two-stroke twin with an electric starter and four-speed box, kept Parilla's name in front of Italian commuters even as the sporting singles carried its reputation abroad. There was also the Bassotto — literally "basset hound" — one of several models named for Giovanni Parrilla's evident fondness for dogs, alongside the Wildcat and the Slughi (a breed of North African sighthound), a small quirk of branding that says something about a company still very much run by one man's personal taste.
Racing
Parilla never had the resources of the larger Italian factories, but it punched well above its size on the track. Between 1949 and 1950 the factory built four magnesium-engined 250cc double-overhead-cam race bikes, exotic machinery for a company barely out of its diesel-pump years, and followed with four more in 1953, mounted in updated frames to run the grueling Motogiro d'Italia and Milano-Taranto road races that were the proving ground for every serious Italian manufacturer of the period. A further seven double-overhead-cam 175cc machines were built for Formula 3 competition.
The high-cam singles proved themselves in exactly this kind of long-distance, high-speed road racing. Giuseppe Rottigni won the 1957 Motogiro d'Italia riding a 175cc Parilla, and the following year Giovanni Parrilla sent him to race in America, at Daytona. Accounts of that Daytona trip vary — period sources describe the 175cc Parilla getting the better of larger, more fancied machinery, but exactly which class it ran in and by what margin it won differs from one telling to the next, so it's fairest to say the 175 acquitted itself impressively against expectations rather than claim a precise, undisputed result.
Parilla's American racing profile grew through the early 1960s largely through privateers and tuners rather than factory effort. At Daytona in February 1964, in a 250cc Grand Prix that saw the favored Yamahas retire with seized engines and which was eventually won by Englishman Alan Shepherd on an MZ, expatriate rider Ron Grant took second place aboard a five-speed Parilla Gran Sport — essentially a race-tuned 250 GS built by tuner Orin Hall. Hall's shop became something of an unofficial competition department for Parilla on the American West Coast; another of his machines, nicknamed "Gadget 1," carried rider Norris Rancourt to two AFM championships in the early 1960s. Off-road, the 250cc Wildcat Scrambler earned a reputation as the most powerful machine in its class, a legitimate contender against home-grown American iron in scrambles competition through the early 1960s.
Ownership, Collapse, and the End of the Line
By the early 1960s, Giovanni Parrilla was looking for a way out. In 1963 he sold the company to an industrial group called Società Industriale Lombarda, or SIL, hoping the deal would give Parilla the capital and stability to keep growing. It didn't work out that way. SIL ran into its own financial trouble and went into liquidation in 1964, taking Parilla down with it.
In the United States, the main channel for Parilla motorcycles was Cosmopolitan Motors of Philadelphia, which imported and sold a dozen or so different Parilla models over the years and became the brand's principal American agent by the late 1950s. After the parent company collapsed into receivership, Cosmopolitan bought up remaining inventory from various sources and kept selling and servicing Parillas for a couple more years, a quiet tail end to the American chapter of the story. Among the American-market bikes was the 250cc GS, built specifically for the U.S.; there is conflicting information about how many actually reached American shores, and the figure is best treated as folklore rather than settled fact.
Giovanni Parrilla himself had already stepped away from day-to-day control before the end. The company experimented in the early 1960s with a 125cc rotary-valve two-stroke paired to a five-speed gearbox, an interesting technical direction that never reached production, and the original Parilla firm folded in 1967. Even after his departure, Parrilla's name didn't disappear entirely: in 1966 he was involved in building MP — Moto Parilla — off-road machines powered by a vertical single-cylinder two-stroke producing around 17 horsepower, a brief coda to a career that had started with spark plugs and diesel pumps two decades earlier.
The Marque Today
For decades after 1967, Parilla existed only as a name collectors traded in hushed, appreciative tones — a small Milanese firm that had built genuinely sophisticated small-displacement engines and raced them credibly against much larger rivals, then vanished. Among people who collect and restore Italian motorcycles, that reputation has held. Parilla is widely regarded as a cult brand: the high-cam singles in particular are prized less for rarity alone than for the cleverness of the engineering and the fact that the company's competition history, modest as its resources were, was entirely real.
The name resurfaced in 2017, though in a very different form. Filippo Beltrami revived Moto Parilla as a maker of high-end electric bicycles, drawing on the historic name to launch models including the Carbon, the folding Trilix, and the Tricolore electric mountain bike, each assembled by hand rather than mass-produced. It's a long way from a 175cc high-cam single howling down the Milano-Taranto route, and the modern company makes no pretense of building motorcycles. But it means the Parilla name, born in a small repair shop on the edge of Milan and carried to Daytona by a 175cc single nobody expected much from, is still on new machines rolling out of Italy — and the originals, meanwhile, remain exactly what generations of collectors have decided they are: some of the most interesting small-bore motorcycles Italy ever built.
