Casalini Sulky

Also known as Willam Sulky

A steel car in a class of plastic ones, its single front wheel steered through a chain and sprockets, and in production for 25 years, longer than most of its rivals.

How big is it?

True proportion

1.85 m

It is 1,120 mm shorter than a Fiat 500, about 1.1 adults laid end to end.

  • 1.15 m wide
  • One seat at first, two in the enlarged body
Drawn at true proportion. The track is 3.6 metres long; the adult stands at the same scale. The Peel P50 is the smallest production car, on every page for comparison.

The story

History

Giovanni Casalini founded his company at Piacenza in 1939.source 1source 2 For its first decades it made things to do with transport but not cars: in the 1950s a moped, the David, and then, because customers asked for them, motor tricycles.source 1source 2 The Sulky was presented at the Milan Cycle and Motorcycle Show in 1969.source 1 The German Wikipedia says production began in 1971; both can be true if the show car came first.source 3

It was an Italian microcar sold in France as a voiturette sans permis, a licence-free car, and almost everything else in that class was glass fibre; the Sulky had a self-supporting body of sheet steel.source 1source 2 The first one seated one person, with a generous boot, on 12-inch wheels. A 50 cc or 60 cc Minarelli two-stroke hung out behind the rear axle and drove both rear wheels through a three-speed gearbox, started with a pull cord. The driver turned a steering wheel, and a chain and sprockets turned the single front wheel. The brakes were hydraulic.source 1 The English Wikipedia gives the first engine as a 49.6 cc Vespa TL3 instead, but two sources say Minarelli.source 2source 4

A Willam in France

Most Sulkys were sold in France, Austria, the Netherlands and Portugal.source 1 In France it is a familiar car because Willam, the Lambretta importer who also sold the Willam City, put its own name on it.source 1source 4 The English Wikipedia says a four-wheeled “Willam Lambretta” was built for export only; the Weiner museum says that four-wheeler, from 1980, was called the Bretta or the David in France, and came as a Break as well.source 2source 4

With sales of 1000 per year, Casalini long outlived the other Italian makes.

Growing a second seat

The first and biggest change, the old site says, was to make the Sulky bigger without changing its name and hardly its profile. It gained a real second seat, and the steering wheel moved to a more usual position.source 1 The bigger body made room for a fourth wheel. The three-wheeler stayed in the catalogue with the new body, but the four-wheeler took most of the sales.source 1 Engines came from BCB, Minarelli and Sachs at 50 cc, with 125 cc units too, manual or automatic, and finally a 325 cc Lombardini diesel. The late cars had plastic bumpers and a dummy grille, separate seats, outsize rear lamps and the door handles of a Fiat Ritmo.source 1

The collector behind the original microcarfan.com put its long life down to good timing, sound construction, classic shapes and keeping up with fashion.source 1

After the Sulky

The last Sulky left the line in 1994. Its replacement, the Kore 500, was built to suit Europe’s ever stricter rules.source 1source 2 Italy adopted the European quadricycle directive that year, and Casalini went on to the Sulkydea (1996), the Ydea (2000), a new car called Sulky (2008), the M10 (2010) and the Kerry utility.source 2 The German Wikipedia lists a later M20 range, including an M20 Speciale of 2021 limited to 11 cars.source 3 Casalini still trades, and calls itself one of the oldest microcar makers in the world.source 2

Famous for

Three points

  1. Twenty-five years

    From the Milan show of 1969 to 1994, longer than most of its rivals lasted.

  2. Steel, not plastic

    A sheet-steel body in a class almost entirely of glass fibre.

  3. Steering by chain

    On the first cars the wheel turned the single front wheel through a chain and sprockets.

Survivors and collecting

Today

A 1977 Willam Sulky, the IIF described in the specification, was in the Bruce Weiner Microcar Museum.source 4 No survivor count, club or serious auction result has been found. The firm itself carries on, its present-day quadricycles the Sulky’s successors.source 2source 3
