The 1972 Aermacchi 350 TV model is a classic motorcycle manufactured by the Aermacchi company and corresponded to the classic Aermacchi 350 TV series. It is the first model of the Aermacchi 350 TV generation to spread worldwide, counting today 51 years since its launch on the market.

To make its specs more concrete, it has stock tire sizes 3.0-19 on the front and 3.5-18 on the rear wheel. In this article we will take a closer look at the classic 1972 Aermacchi 350 TV motorcycle.


The 1972 Aermacchi 50cc motorcycle was manufactured by Aermacchi, an Italian aircraft manufacturer. The manufacturing company formerly known as Aeronautica Macchi was founded by Giulio Macchi in Varese, northwestern Lombardy, in 1912. As the factory is located on the shores of Lake Varese, the company began manufacturing a series of Nieuport models and seaplanes for Italy. military. In 1971 the company began manufacturing the 250cc and 350cc two-stroke twin-cylinder racers with Aermacchi as chief engineer and designer. The first 250 cc model was a real hit as it ran at high speed with 46 horsepower at 11,000 rpm and weighed only 250 pounds. After Harley-Davidson heard about Aermacchi’s work, they decided to fund this motorcycle racing development at the Aermacchi factory. Harley-Davidson decided to use these 250cc two-stroke twins in Grand Prix competition, which helped win their only Grand Prix medals and all four World Championships; 250cc World Championship in 1974, 1975, 1976 and 350cc World Championship in 1976. The fast 250cc motorcycle became very popular in production racing and was gradually improved between 1969 and 1974 to a 350cc version.

After World War II, Harley-Davidson began manufacturing three-wheelers and utility motorcycles as a solution to fill the post-war shortfall with affordable and efficient transportation. After experiencing fierce competition from Japanese motorcycles, Harley-Davidson decided to introduce something competitive to the small motorcycle industry. Possible options included further development of their 165cc single-cylinder two-stroke bike or submitting an all-new bike design. Using the engineering skills of Aermacchi, they have built a formidable and capable 250cc motorcycle with impressive road performance and several opportunities for further development. After agreeing to include a Sportster frame in the 250cc speed model, Aermacchi’s former company, Aeronautica Macchi, sold 50% of its shares to Harley-Davidson. The year 1962 ushered in a new era for the Harley/Aermacchi era. Working closely together, the fast 250cc quickly became the most popular bike in production racing, and a unique design was included in the cycle. Later, the bike was now available in American and European versions. Since upgrading to a 350cc version, the bike has been fitted with a four-speed gearbox, a 74 x 80 engine that delivers a maximum of 25hp at 7000rpm, with a top speed of around 145 km/h.

Engine and gearbox

The classic 1972 Aermacchi 350cc bicycle has a 350cc single cylinder engine mated to a 4-speed transmission and produces 25 horsepower at 2000 rpm. This powerful engine comes to life with a kick start and a foot shifter placed on the right side of the bike. When introduced in 1961 and after the collaboration between Aeronautica Macchi and Harley Davidson, the 1972 motorcycle was equipped with a 250 cc horizontal single-cylinder four-stroke engine. A lot changed with the 1972 Aermacchi bike, including a 350cc air-cooled OHV horizontal single cylinder and a 4-speed gear transmission. In addition, this classic model is now available in Street and on/off-road versions to adapt to the riding preferences of each rider. Another great addition to the 1972 Aermacchi bike is the choke that actually works once the bike warms up. As a result, the manufacturing company advises letting the bike warm up completely before enjoying your ride.

Power and displacement

Over the years since its launch, a number of modifications have been made to the chassis and engines of the classic Aermacchi series. The first was the conversion of the original long-stroke 250cc engine with the 293cc version which featured short-stroke dimensions (72 x 61mm). Later, the 72 x 61 mm engine was replaced by a larger and more powerful 344 cc engine with dimensions of 74 x 80 mm. As a result, the 1972 Aermacchi motorcycle became the smallest classic motorcycle made by a major American motorcycle manufacturer. On ignition, the engine responds immediately with an impressive rate of acceleration. However, compared to rival Japanese models, the transmission responds a little slower. The inclusion of a short stroke allows the bike to cope well with incredible speeds of 140 km/h and produce 27 horsepower at 2,000 rpm. The 1972 Aermacchi 350cc bike comes with the signature banana yellow fenders and a fuel tank with a fluorescent orange paddle. The motorcycle body is presented in a matte black lockable storage box under the well-padded black vinyl seat and a gloss black frame. Also, scratches and wear are clearly visible on the chrome trim.

Last words

The classic 1972 Aermacchi 350 TV bicycle was made by Aermacchi, who was also an aircraft builder for the Japanese military. Initially, the manufacturing company started with the 250cc horizontal single cylinder engine. After the American company Harley Davidson bought 50% of the shares, they changed the name of the motorcycle to Wisconsin but quickly changed the name to Sprint. In the late 1960s, the factory brands decided to upgrade their 250cc motorcycle with a 350cc engine to help keep up with rival Japanese brands. According to Bringatrailer, the 1972 Aermacchi 350 TV Sprint bike now retails for an average price of $6,100.
