Introducing the 1945 Ariel NH 350: A Timeless Classic The 1945 Ariel NH 350 stands as a testament to British engineering and design in the post-war motorcycle era. Positioned as an all-rounder, this charming machine perfectly balances practicality and performance, appealing to both riders looking for a reliable commuting option and enthusiasts seeking a touch of vintage flair. With its elegant dark red finish and classic aesthetic, the Ariel NH 350 is not just a motorcycle; it is a piece of history that captures the spirit of its time, embodying the resilience and innovation of a nation recovering from war. Engine Performance and Riding Dynamics At the heart of the NH 350 lies a robust 346cc single-cylinder, four-stroke engine that churns out a respectable 19.5 horsepower at 5800 RPM. This engine, characterized by its 6.2:1 compression ratio and bore-stroke dimensions of 72.0 x 85.0 mm, delivers a smooth and responsive ride. Riders can expect a top speed of 117 km/h (72.7 mph), making it ideal for both leisurely country rides and more spirited jaunts. The air-cooled engine, coupled with a 4-speed gearbox and a dry, multiplate clutch, allows for seamless gear transitions that enhance the overall riding experience. The NH 350’s power-to-weight ratio of 0.1226 HP/kg ensures that riders can enjoy a lively performance, complemented by the stability offered by its semi-double cradle frame. Key Features and Innovative Technology The Ariel NH 350 is replete with features that reflect the technological advancements of its time. Its telescopic front fork and plunging rear suspension provide a comfortable and controlled ride, allowing it to tackle various terrains with ease. The expanding drum brakes at both the front and rear ensure reliable stopping power, which is crucial for maintaining safety on the road. With a fuel capacity of 11 liters (2.91 gallons), riders can enjoy extended journeys without frequent stops for refueling. Additionally, the NH 350 employs a classic kick starter, adding to its vintage charm and engaging the rider in the mechanical experience of starting the engine. **
