Overview

Introducing the 1959 Ariel NH 350 Red Hunter, a quintessential example of British motorcycle craftsmanship that has left an indelible mark on the world of two-wheeled enthusiasts. Positioned in the allround category, this bike was designed not only for the daily commuter but also for the adventurous spirit. Sporting a classic aesthetic that beautifully embodies the era, the Red Hunter is more than just a motorcycle; it’s a piece of history that captures the essence of motorcycling in the late 1950s. With its rich dark red finish, this bike stands out while evoking nostalgia for simpler times when riding was about the journey, not just the destination. At the heart of the NH 350 is its robust single-cylinder, four-stroke engine with a displacement of 346 cc. This powerplant delivers a respectable 19 horsepower at 5,600 RPM, allowing riders to experience a top speed of 124.7 km/h (77.5 mph). Thanks to its 7.0:1 compression ratio and Amal monoblock carburettor, the engine provides smooth acceleration and a delightful riding experience. The 4-speed gearbox, paired with a dry, multiplate clutch, ensures that gear changes are seamless, allowing riders to navigate through urban landscapes or stretch their legs on open roads. With a fuel consumption rate of just 2.69 litres per 100 km (an impressive 87.44 mpg), the Red Hunter is as economical as it is exhilarating, making it a sensible choice for long rides. The NH 350 is not just about performance; it comes equipped with features that reflect advanced engineering for its time. The semi-double cradle frame provides rigidity and enhances handling, while the telescopic front fork and plunger rear suspension offer a smooth ride over various terrains. Safety is also paramount, with expanding drum brakes on both the front and rear, ensuring reliable stopping power. The bike’s modest weight of 160 kg (352.7 pounds) and a seat height of 787 mm (31 inches) make it accessible to a wide range of riders, enhancing its appeal. Additionally, the kick starter adds a touch of authenticity for those who appreciate the classics. **

Pros

  • Timeless Aesthetic: The classic design and rich dark red color make it a head-turner, perfect for vintage motorcycle enthusiasts.
  • Fuel Efficiency: With an impressive 87.44 mpg, it’s economical for both daily commuting and long-distance touring.
  • Smooth Handling: The combination of a lightweight frame and robust suspension ensures a comfortable and responsive ride.

Cons

  • Limited Power: While sufficient for cruising, the 19 HP may feel underwhelming for riders seeking high performance or fast acceleration.
  • Kick Start Only: The absence of an electric starter can be inconvenient, especially in colder weather or for novice riders.
  • Drum Brakes: While reliable, the drum brake system may not offer the same stopping power or responsiveness as modern disc brakes, potentially affecting safety in emergency situations.
