Overview

### The 1955 Harley-Davidson Hummer: A Timeless Classic on Two Wheels The 1955 Harley-Davidson Hummer is a captivating blend of nostalgic charm and rugged practicality, making it a standout in the realm of naked bikes. As a lightweight, entry-level motorcycle, the Hummer was designed to appeal to both new riders and seasoned enthusiasts looking for a fun, economical machine. With its iconic styling and approachable size, this bike has carved out a lasting legacy in the Harley-Davidson lineage, embodying the spirit of freedom and adventure that the brand is known for. Under the sleek, vintage exterior lies a spirited, single-cylinder, two-stroke engine boasting a displacement of 125 ccm (7.63 cubic inches). With a compression ratio of 6.6:1, the Hummer delivers a commendable top speed of 80.5 km/h (50.0 mph). The carburetted powerplant is ignited via a reliable magneto, providing a responsive throttle feel that makes zipping through city streets or cruising along country roads an absolute joy. The lightweight frame, tipping the scales at just 77.1 kg (170 lbs), enhances the motorcycle's agility, allowing riders to effortlessly navigate tight corners and enjoy a connected riding experience that few modern machines can replicate. The Hummer is equipped with several key features that reflect the engineering prowess of its time. The front suspension combines girder and rubber spring technology, offering a surprisingly smooth ride despite the rigid rear end. Both front and rear drum brakes provide dependable stopping power, ensuring that this nimble bike can handle itself well in various riding conditions. With a fuel capacity of 6.60 litres (1.74 gallons), the Hummer is also surprisingly economical, making it an ideal choice for those who relish long rides without frequent stops at the pump. **

Pros

  • Lightweight and Nimble: At only 77.1 kg, the Hummer is easy to handle, making it perfect for both novice and experienced riders.
  • Classic Aesthetic: Its vintage design and iconic Harley-Davidson branding appeal to collectors and enthusiasts alike.
  • Economical Performance: With a small engine and efficient fuel consumption, the Hummer offers great value for those who enjoy budget-friendly rides.

Cons

  • Limited Power: The 125 ccm engine may not satisfy riders looking for high-performance capabilities or highway cruising power.
  • Rigid Rear Suspension: While it enhances the classic look, the rigid rear may not provide the comfort that modern suspension systems offer, especially on rough terrain.
  • Basic Features: Lacking modern conveniences such as electric start or advanced braking systems, the Hummer requires a more hands-on approach to riding.
