Overview

Introducing the 1961 Aermacchi H-D 250 Ala Azzurra, a quintessential motorcycle that captures the spirit of early 60s Italian craftsmanship combined with American flair. Designed for the allround rider, this model emerged from a collaboration between Aermacchi, an established name in the motorcycle scene, and Harley-Davidson, which sought to tap into the growing demand for lightweight and versatile bikes. In an era when two-stroke engines predominated, the Ala Azzurra offered a refreshing alternative with its reliable four-stroke single-cylinder engine, appealing to both novice and experienced riders looking for a dependable yet spirited ride. Under the skin, the Ala Azzurra houses a 246cc single-cylinder engine that produces a respectable 13.7 horsepower at 6,500 RPM. This power output translates into a top speed of 125 km/h (77.7 mph), making it more than capable of keeping pace with urban traffic while still providing a thrilling ride. The engine’s 7:1 compression ratio and air-cooled design contribute to its robustness, allowing riders to enjoy longer journeys without overheating concerns. The 4-speed gearbox, paired with a wet multiplate clutch, ensures smooth transitions, while the chain final drive provides efficient power delivery. The bike's weight of just 114 kg (251.3 lbs) contributes to its agility, making navigating through twisty roads or city streets a breeze. The Aermacchi H-D 250 Ala Azzurra is not just about performance; it also boasts features that enhance rider comfort and control. The single cradle frame provides a solid foundation, while the telescopic front suspension and swingarm rear suspension with dual shocks guarantee a smooth ride over various terrains. Its drum brakes—both front and rear—offer reliable stopping power, although they require a bit of extra finesse compared to modern discs. With a fuel capacity of 18 liters (4.76 gallons), the Ala Azzurra promises longer rides without frequent fill-ups, making it an ideal companion for weekend excursions or daily commutes. **

Pros

  • Lightweight and agile, ideal for city riding and twisty roads.
  • Reliable four-stroke engine with decent power output for its class.
  • Classic aesthetics combined with practical features, appealing to vintage motorcycle enthusiasts.

Cons

  • Drum brakes may lack the stopping power and response of modern disc systems.
  • Limited horsepower may not satisfy riders seeking high-speed performance.
  • Kick starter can be cumbersome for those accustomed to electric starters, especially in modern riding scenarios.
