Key Features and Technology

The Ariel 4G isn’t just about power; it’s also a marvel of engineering finesse. Its tubular single-loop frame offers a sturdy yet lightweight foundation, contributing to its agile handling. The motorcycle is equipped with a telescopic front fork and a plunger-link rear suspension, ensuring a comfortable ride over varying terrains. With drum brakes at both the front and rear, riders can expect reliable stopping power despite the bike's vintage roots. The 23-litre fuel tank not only provides ample range but also complements the aesthetic with its classic red and silver color options. The kick starter adds a touch of nostalgia, reminding riders of the simpler, more mechanical side of motorcycling.
