Overview

Introducing the 1959 Ariel HT5 500 Trials Motorcycle Step back in time to the late 1950s, an era that saw the rise of lightweight, agile motorcycles designed for the rugged demands of off-road riding. Amongst the iconic machines of this period stands the 1959 Ariel HT5 500 Trials motorcycle, a model that beautifully marries classic aesthetics with practical engineering for the trials enthusiast. With its robust single cradle frame and minimalist design, the HT5 carved out a niche in the burgeoning enduro-offroad category, appealing not only to competitive riders but also to casual adventurers seeking the thrill of tackling challenging terrains. Engine Performance and Riding Characteristics At the heart of the Ariel HT5 is a spirited single-cylinder, four-stroke engine boasting a displacement of 497 cc. This powerplant delivers an impressive 24.94 HP at 6000 RPM, providing a punchy yet manageable power curve that rewards both seasoned riders and those new to the trials scene. The carburettor-fed engine is air-cooled, maintaining optimal temperature even during extended rides, while the 4-speed gearbox allows for seamless shifting, ensuring that riders can harness every ounce of performance when navigating through rocky paths or steep inclines. Weighing in at a mere 132 kg (291 lbs), the HT5 offers an exhilarating power-to-weight ratio of 0.1889 HP/kg, making it incredibly responsive and nimble on the trails. Key Features and Technology The Ariel HT5 is equipped with features that underline its trials-focused design. The telescopic front forks and swing arm rear suspension with hydraulic dampers provide excellent shock absorption, enabling the bike to handle the roughest of terrains with ease. The expanding drum brakes, both front and rear, offer reliable stopping power, instilling confidence as riders tackle steep descents or tight turns. With a generous ground clearance of 220 mm (8.7 inches), the HT5 is adept at avoiding obstacles while maintaining stability. The classic kick-starter not only adds to its vintage charm but ensures that the bike is always ready to conquer the next adventure. **
